                                 PROXY STATEMENT

                         ANNUAL MEETING OF STOCKHOLDERS
                            TO BE HELD APRIL 23, 1997


     This Proxy  Statement is furnished in connection  with the  solicitation of
proxies by the Board of Directors of Data Transmission  Network  Corporation,  a
Delaware  corporation  (the  Company"),  to be used  at the  Annual  Meeting  of
Stockholders (the "Meeting") to be held at the Holiday Inn - Old Mill, 655 North
108th Avenue, Omaha, Nebraska on Wednesday,  April 23, 1997, at 10:00 A.M. Omaha
time.  Stockholders  of  record at the  close of  business  on March 5, 1997 are
entitled  to  notice  of and to vote at the  Meeting.  The  Company's  principal
executive  offices  are  located at 9110 West  Dodge  Road,  Suite  200,  Omaha,
Nebraska 68114.

                                     PROXIES

     Proxies are being  solicited  by the Board of Directors of the Company with
all costs of the  solicitation  to be paid by the Company.  If the  accompanying
proxy is executed  and  returned,  the shares  represented  by the proxy will be
voted as specified therein. A stockholder may revoke any proxy given pursuant to
this  solicitation  by delivering  to the Company prior to the Annual  Meeting a
written  notice of  revocation or by attending the Meeting and voting in person.
This notice of Annual Meeting of Stockholders,  proxy statement and accompanying
proxy card are first being mailed to stockholders on or about March 14, 1997.

                                VOTING SECURITIES

     At March 5, 1997, the Company had issued and outstanding  11,063,020 shares
of the Company's $.001 par value common stock.  The Company effected a three for
one stock split on June 28, 1996, for  shareholders  of record on June 14, 1996.
The  Company  has  no  other  class  of  voting  securities  outstanding.   Each
stockholder  voting in the election of directors may cumulate such stockholder's
votes and give one  candidate a number of votes equal to the number of directors
to be elected  multiplied  by the  number of votes to which  such  stockholder's
shares are entitled, or may distribute such votes on the same principle among as
many candidates as the stockholder  chooses,  provided that votes cannot be cast
for more than the total number of  directors  to be elected at the Meeting.  The
seven  nominees  receiving  the most  votes at the  Meeting  will be  elected as
directors.  Each share has one vote on all other matters. An affirmative vote of
a majority of the shares  present in person or by proxy and  entitled to vote at
the  meeting is  required  for  approval  of all items  being  submitted  to the
stockholders  for their  consideration.  

     In accordance  with  Delaware  law, a shareholder  entitled to vote for the
election of  directors  can  withhold  authority to vote for all nominees or for
certain nominees for directors. Abstentions from either or both of the proposals
to amend the Company's  Employee Stock Option Plan or to ratify the  appointment
of  auditors  are  treated as votes  against  the  particular  proposal.  Broker
non-votes  on either or both of the  proposals to amend the  Company's  Employee
Stock Option Plan or to ratify the appointment of auditors are treated as shares
as to which voting power has been  withheld by the  beneficial  holders of those
shares and,  therefore,  as shares not  entitled  to vote on the  proposal as to
which there is the broker non-vote.

                                 PROPOSAL NO. 1

                              ELECTION OF DIRECTORS

     At the Meeting, the stockholders will elect a board of seven directors for
a term extending until the 1998 annual meeting of stockholders of the Company 
and until their respective successors have been elected and qualify. The Board
of Directors has nominated for election or re-election as directors:  Roger R. 
Brodersen, Robert S. Herman, David K. Karnes, J. Michael Parks, Jay E. Ricks, 
Greg T. Sloma and Roger W. Wallace. All of the nominees presently are serving as
directors of the Company. Proxies may be voted for seven directors.

     If any  nominee  is unable to serve,  the shares  represented  by all valid
proxies  will be voted  for the  election  of such  substitute  as the  Board of
Directors  may  recommend  or the Board of  Directors  may amend the By-Laws and
reduce the size of the Board. At this time, the Board knows of no reason why any
nominee might be unavailable to serve.

     Set forth below is certain information as of March 5, 1997, with respect to
the nominees for election as directors of the Company.  The information relating
to their  respective  business  experience  was furnished to the Company by such
persons.

present at one meeting of the Board of Directors,  all directors attended all of
the meetings of the Board of  Directors,  and related  committees  on which they
served. The Company does not have a Standing Nominating Committee.

     The Audit Committee  recommends the selection of the independent  auditors,

and any recommendations made by them relating to internal financial controls and
procedures.  Members of the Audit Committee, which met twice during fiscal 1996,

     The Compensation  Committee reviews and makes  recommendations to the Board

Directors Compensation
- ----------------------

     During  fiscal 1996,  each member of the Board of Directors  who was not an
employee  of the Company  received  $1,000 for each Board of  Directors  meeting
attended,  $400 for each Audit  Committee  meeting  attended  and $1,000 for the
Compensation  Committee meeting attended.  Non-employee  members of the Board of
Directors also receive awards under the Company's  Non-Employee  Directors Stock
Option Plan (the "Non-Employee  Directors Plan").  Stock option grants under the
Non-Employee  Directors  Plan are automatic  and occur each time a  non-employee
director is elected, re-elected or appointed a director of the Company. In 1996,
David K. Karnes,  J. Michael  Parks and Jay E. Ricks each  received an option to
purchase  6,000 shares of the  Company's  common  stock at an exercise  price of
$17.33 per share.  The  Non-Employee  Directors Plan has been amended for fiscal
year 1997 to reduce  from 6,000 to 4,500 the number of shares for which  options
are to be awarded to each non-employee  director.  The exercise price of options
granted under the  Non-Employee  Directors  Plan is the fair market value of the
common stock on the date of the option grant.

(2)  This amount  includes  225,000 shares  underlying a replacement  option
     issued to Mr.  Brodersen  in exchange  for the  surrender  of  outstanding,
     unexpired and unexercised options to acquire an aggregate of 117,999 shares
     of common stock of this  corporation  previously  awarded to Mr.  Brodersen
     under the  Company's  Stock Option Plan of 1989.  The  surrendered  options
     exercisable  for  117,999  shares  were  considered  for  tax  purposes  as
     Incentive  Stock  Options  (ISO's),  whereas,  the  replacement  option for
     225,000  shares is  considered  for tax purposes as a  Non-Qualified  Stock
     Option.  The weighted  average  exercise price per share of the surrendered
     options was $6.28,  while the exercise price of the replacement  option was
     the fair market  value of the common stock on January 5, 1996 or $15.50 per
     share.

(3)  This amount represents shares underlying an option awarded to Mr. Sloma
     on May 13, 1996 for his performance related to the acquisition of Broadcast
     Partners by the Company.

(4)  As suggested by the Securities & Exchange  Commission's  rules on executive
     compensation,  the Company used the Black-Scholes model of option valuation
     to determine  grant date present  value.  The Company does not  necessarily
     agree that the Black-Scholes  model can properly  determine the value of an
     option.  The actual value,  if any, an executive may realize will depend on
     the  excess  of the stock  price  over the  exercise  price on the date the
     option is exercised,  so that there is no assurance that the value realized
     will be at or near the value estimated by the Black-Scholes model.

                          COMPENSATION COMMITTEE REPORT
                            ON EXECUTIVE COMPENSATION

Compensation Philosophy
- -----------------------

     The Company strives to apply a consistent  philosophy on  compensation  for
all  employees,  including  senior  management.  The  goals of the  compensation
program are to directly link compensation  with corporate  profitability and the
enhancement of the  underlying  value of the Company's  business.  The following
objectives are used by the Company and the Compensation  Committee as guidelines
for compensation decisions:

         o Provide a  competitive  total  compensation  package  that allows the
           Company to attract and retain the best people possible. 

         o The Company pays for  performance.  Employees are rewarded based upon
           corporate  performance,  business  unit  performance  and  individual
           performance.

         o Provide  variable  compensation  programs  that are  linked  with the
           performance of the Company and that align executive compensation with
           the interests of shareholders.

Compensation Program Components
- -------------------------------

     The Committee annually reviews the Company's compensation program to ensure
that pay levels and  incentive  opportunities  are  competitive  and reflect the
performance  of the Company.  The  components  of the  compensation  program for
executive  officers,  which are comparable to those used for all employees,  are
outlined below.

     Base  Salary - Base pay  levels are  determined  by  reviewing  competitive
positions in the market,  including  comparisons with companies of similar size,
complexity and growth rates. Modest increases in base salary were recommended by
senior  management for fiscal 1996 for the Chief Executive Officer and the other
executive  officers named in the Summary  Compensation  Table, and the Committee
acted in accordance with this recommendation.

     Annual  Incentive  Compensation  - The  large  majority  of  the  Company's
employees,  including the  executive  officers,  participate  in an annual bonus
plan. For fiscal 1996, the bonus pool was eight percent of the Company's  income
before  income  taxes  and  depreciation  and  amortization  expenses  of  which
approximately 75% was earned and will be paid. The five executive officers named
in the Summary Compensation Table received approximately thirty-three percent of
this bonus pool.

     Stock Option  Program - The purpose of this program,  which is available to
the  large  majority  of  employees,  is to  provide  additional  incentives  to
employees to work to maximize long-term  shareholder value. It also uses vesting
periods to encourage key employees to continue in the employ of the Company. The
number of stock options  granted to executive  officers is based on  competitive
practices.

CEO Compensation
- ----------------

     The factors and criteria upon which Mr. Brodersen's  compensation was based
for  fiscal  year  1996 are the same as those  considered  by the  Committee  in
establishing the compensation  program for all of the executive  officers of the
Company  as  outlined  above.  The  annual  base  salary  of Mr.  Brodersen  was
established  by the  Committee on February 29, 1996 for the calendar  year 1996.
The Committee's  decision was based on Mr. Brodersen's  personal  performance of
his duties and on salary  levels to chief  executive  officers of  companies  of
similar size, complexity and growth rates.

      Mr.  Brodersen's 1996 fiscal year incentive cash compensation was based on
the actual financial performance of the Company. His annual cash bonus award was
based on the bonus pool described  above and  represented  approximately  seven
percent of the bonus pool awarded for 1996.

      An option grant for 15,000 shares was awarded to Mr.  Brodersen  under the
Company's  Employee Stock Option Plan based upon his  performance and leadership
with  the  Company.  The  grant  placed  a  significant  portion  of  his  total
compensation at risk,  since the value of the option depends on the appreciation
of the  Company's  common  stock over the option term.  On January 5, 1996,  Mr.
Brodersen also surrendered  unexpired and unexercised options previously awarded
to him under the plan in exchange for a  replacement  option.  Such  replacement
option was not considered as part of the Company's 1996 compensation program. It
was an isolated  occurrence where the Company  obtained  cancellation of options
with  exercise  prices  substantially  below fair market  value by  exchanging a
replacement  option with additional shares and an extended option term, but with
an exercise price equal to the fair market value of the common stock on the date
the replacement option was granted. See Footnote 2 to the table captioned Option
Grants  In  Last  Fiscal  Year  for  additional   information   concerning  such
replacement option.

                                 PROPOSAL NO. 2

                     AMENDMENT TO EMPLOYEE STOCK OPTION PLAN

Description of Employee Stock Option Plan
- -----------------------------------------

     The Company's Stock Option Plan of 1989 (the "Plan") provides for the grant
of  options  to  purchase  shares of the  Company's  common  stock to  full-time
employees of the Company.  The Plan is  administered  by a  subcommittee  of the
Compensation  Committee of the Board of Directors consisting of the non-employee
directors (the "Committee").

     Options  granted  under the Plan are  exercisable  pursuant to a three-year
vesting  schedule  and they  terminate  no later than ten years from the date of
their  grant.  If  employment  ends sooner than the end of an options  specified
exercise period,  the options  terminate six months after the termination of the
participant's  employment for any reason other than  disability or death. In the
event of disability or death, they terminate twelve months after such disability
or death.

     The Plan currently  reserves for issuance 2,100,000 shares of the Company's
common  stock.  The  maximum  number of shares for which  options may be granted
under the Plan was adjusted from 700,000 to 2,100,000 as a result of a three for
one stock  split  effective  June 28, 1997 for  stockholders  of record June 14,
1996. The Board of Directors proposes the adoption of the Fifth Amendment to the
Plan  which  accompanies  this  Proxy  Statement  as  Exhibit  "A"  (the  "Fifth
Amendment").  The  Fifth  Amendment  will  amend  the  Plan by  increasing  from
2,100,000  shares  to  2,800,000  shares  the total  number of shares  for which
options may be granted under the Plan.

     Subject to the express  provisions of the Plan,  the Committee has complete
authority,  in its  discretion,  to interpret the Plan and select those eligible
participants  to whom and the terms  upon which  options  shall be  granted.  No
options shall be granted at an exercise  price less than 100% of the fair market
value of the  shares at the date of the grant.  As of March 5, 1997,  the market
value of the shares of common  stock of the Company,  determined  by the closing
"bid" price of such shares as  reported by the NASDAQ  system for such day,  was
$23.38 per share. No cash consideration is to be received by the Company for the
granting of options pursuant to the Plan.

     In the event of any changes in the number of issued  shares  through  stock
splits, dividends, or other change in capitalization, the total number of shares
under the Plan is to be adjusted  so that the  aggregate  consideration  due the
Company and the value of each benefit shall not change.

Plan Activity
- -------------

     As of March 5, 1997,  options to purchase an aggregate of 388,344 shares of
common stock issued under the Plan had been  exercised,  and options to purchase
1,587,576  shares were  outstanding.  Without  taking into  account the proposed
amendment to the Plan, 124,080 shares remained available for future grants as of
March 5, 1997.

     The table under the caption  "Option  Grants in Last Fiscal Year"  provides
information  with  respect to the grant of  options  under the Plan to the Chief
Executive Officer and the next four most highly  compensated  executive officers
during fiscal year 1996. The following table sets forth  additional  information
with  respect to options  granted  under the Plan during the fiscal year 1996 to
certain groups:

Certain United States Federal Income Tax Information
- ----------------------------------------------------

     The Plan  provides for the  issuance of both  incentive  stock  options and
non-qualified options. The two types of options are subject to differing federal
income tax treatment.  There  generally are no federal  income tax  consequences
either to the  participant  or the Company upon the grant of an option under the
Plan. Upon the exercise of an incentive stock option,  the participant  will not
recognize  any  income  for income tax  purposes,  and the  Company  will not be
entitled to a deduction for income tax purposes, although such exercise may give
rise to a liability on the part of the participant under the alternative minimum
tax  provisions of the Internal  Revenue  Code.  Generally,  if the  participant
disposes of shares  acquired  upon the  exercise of an incentive  stock  options
within two years after the date of grant or one year after the date of exercise,
the  participant  will recognize  compensation  income,  and the Company will be
entitled to a deduction for income tax purposes,  in the amount of the excess of
the fair market  value of the shares of common  stock of the Company on the date
of  exercise  over the option  exercise  price (or the gain upon such  sale,  if
less).  Otherwise,  the Company will not be entitled to any deduction for income
tax purposes upon the disposition of such shares,  and the participant's  entire
gain will be treated as a capital  gain.  Upon the  exercise of a  non-qualified
stock  option,  the amount by which the fair market value of the common stock of
the Company on the date of exercise  exceeds the option exercise price generally
will be taxable to the participant as compensation  income and generally will be
deductible for income tax purposes by the Company.  The disposition of shares of
common stock of the Company acquired upon the exercise of a non-qualified  stock
option  generally will result in a capital gain or loss for the  participant but
will have no tax consequences for the Company.

Amendment To Employee Stock Option Plan
- ---------------------------------------

     The Board of Directors  has  unanimously  approved,  and  recommends to the
stockholders  for their approval and adoption,  the Fifth  Amendment to the Plan
which will increase  from  2,100,000 to 2,800,000 the total number of shares for
which  options  may be  granted  under the  Plan.  The  Board of  Directors  has
determined  that the  ability of the  Company to  continue to attract and retain
highly  qualified  employees will be enhanced by the continued  grant of options
under the Plan and,  accordingly,  recommends  a vote FOR  adoption of the Fifth
Amendment.  The  affirmative  vote of a majority of the shares of the  Company's
common  stock  present in person or by proxy at the meeting is required  for the
adoption of the Fifth Amendment.

     The full text of the amended Plan is available to any  shareholder  without
charge by oral or written request to the Company  Secretary,  Data  Transmission
Network Corporation, 9110 West Dodge Road, Suite 200, Omaha, NE 68114, telephone
(402) 390-2328.  A copy of the Plan document will be sent by first class mail to
the  requesting  party  promptly  upon  receipt of the  request  by the  Company
Secretary.

                                 PROPOSAL NO. 3

                       APPROVAL OF APPOINTMENT OF AUDITORS

     The Board of Directors has, upon the recommendation of the Audit Committee,
appointed  the firm of  Deloitte & Touche LLP to audit the  Company's  financial
statements for the fiscal year ending December 31, 1997, subject to ratification
by the  stockholders  of the  Company.  Deloitte  &  Touche  LLP  served  as the
Company's auditors for the 1996 fiscal year.

     Ratification of the appointment of the  independent  auditors  requires the
affirmative vote of a majority of the shares of Common Stock present,  in person
or by proxy, and voting at the Meeting.  If the  stockholders  should not ratify
the appointment of Deloitte & Touche LLP, the Board of Directors will reconsider
the appointment.

     A representative  of Deloitte & Touche LLP is expected to be present at the
Meeting,  will have an opportunity  to make a statement if desired,  and will be
available to respond to appropriate stockholder questions.

     The  Board  of  Directors  recommends  a  vote  FOR  the  approval  of  the
appointment of Deloitte & Touche LLP as independent auditors for the Company.

                          TRANSACTIONS WITH MANAGEMENT

    No reportable  transactions  occurred during fiscal 1996 between the Company
and its officers and directors.

           COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     The  following  directors  served  on  the  Compensation  Committee  of the
Company's Board of Directors:  David K. Karnes,  J. Michael Parks,  Jay E. Ricks
and Greg T.  Sloma.  Mr.  Sloma,  because he is an officer  and  employee of the
Company,  abstains from all votes dealing with officer compensation.  Also, only
Mr.  Karnes,  Mr.  Parks and Mr.  Ricks are  members  of the Stock  Option  Plan
Subcommittee of the Compensation Committee which administers the Company's Stock
Option Plan of 1989.
                                 
                  STOCKHOLDER PROPOSALS FOR 1998 ANNUAL MEETING

     Proposals of stockholders  for which  consideration  is desired at the 1998
Annual  Meeting of  Stockholders  must be  received by the Company no later than
December 31, 1997,  in order to be  considered  for  inclusion in the  Company's
proxy  statement and form of proxy relating to such meeting.  Any such proposals
shall be  subject  to the  requirements  of the proxy  rules  adopted  under the
Securities Exchange Act of 1934, as amended.

             SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

     Section  16(a) of the  Securities  Exchange  Act of 1934,  as amended  (the
"Exchange  Act"),  requires  the  Company's  directors,  executive  officers and
holders  of more  than  10% of the  Company's  common  stock  to file  with  the
Securities and Exchange  Commission  initial reports of ownership and reports of
changes in ownership of common stock and other equity securities of the Company.
The Company  believes that during the fiscal year ended  December 31, 1996,  its
executive  officers,  directors  and  holders of more than 10% of the  Company's
common  stock  complied  with all Section  16(a) filing  requirements,  with the
following exception.  James J. Marquiss,  an officer,  filed one late Form 4 for
the month of November 1996 with respect to a single transaction involving shares
of the  Company's  Common  Stock sold by him during such month.  In making these
statements,  the  Company  has  relied  solely  upon a  review  of Forms 3 and 4
furnished to the Company  during its most recent fiscal year,  Forms 5 furnished
to the  Company  with  respect  to its most  recent  fiscal  year,  and  written
representations from reporting persons that no Form 5 was required

                                  OTHER MATTERS

     The Board of  Directors  is not aware of any  business  to come  before the
Meeting  other  than  those  matters  described  above in the  Proxy  Statement.
However,  if any other  matters  should  properly  come before the meeting,  the
persons  named  in the  accompanying  form  of  proxy  will  have  discretionary
authority  to vote all proxies  with respect  thereto in  accordance  with their
judgement.

                                  MISCELLANEOUS

     The cost of  solicitation  of  proxies  will be borne by the  Company.  The
Company will,  upon request,  reimburse  brokerage  firms and other  custodians,
nominees and  fiduciaries  for reasonable  expenses  incurred by them in sending
proxy  material  to the  beneficial  owners  of Common  Stock.  In  addition  to
solicitations by mail, directors, officers, and regular employees of the Company
may solicit proxies  personally or by telegram or telephone  without  additional
compensation.  The  Company  has  retained  First  National  Bank of Omaha,  the
Company's stock transfer agent, to assist in the  distribution  and solicitation
of proxies at a cost of  approximately  $3,000,  including the  reimbursement of
certain expenses.

     The  Company's   Annual  Report  to   Stockholders,   including   financial
statements,  has been  mailed to all  stockholders  of record as of the close of
business on March 5, 1997. Any  stockholder  who has not received a copy of such
Annual  Report may obtain a copy by writing the Company.  Such Annual  Report is
not to be treated as a part of this proxy  solicitation  material  nor as having
been incorporated herein by reference.

     Notwithstanding  anything to the contrary set forth in any of the Company's
previous  filings under the Securities Act of 1933, as amended,  or the Exchange
Act that might incorporate  future filings,  including this Proxy Statement,  in
whole  or in  part,  the  Compensation  Committee  Report  on  page  10 and  the
Performance Graph on page 9 shall not be incorporated by reference into any such
filings.

                                    PREAMBLE

     Data  Transmission  Network   Corporation,   a  Delaware  corporation  (the
"Company"),  adopted the Data Transmission Network Corporation Stock Option Plan
of 1989 (the "Plan")  effective as of February 15, 1989. The Plan was previously

adjusted to reflect the effect of a three for one stock split implemented by the
Company on June 28, 1997. Section 1 of Article III of the Plan provides that the
Board of  Directors of the Company or any  authorized  committee of the Board of
Directors  may from  time to time  amend  the  Plan  with  shareholder  approval
required  under  certain  circumstances.  Except as modified by or  specifically
defined in this Fifth Amendment,  capitalized terms used in this Fifth Amendment
shall have the meanings given to such terms in the Plan.

                                    AMENDMENT

     Subject to ratification  and approval by the shareholders of the Company at
their  annual  meeting  to be held on the 23rd day of April,  1997,  the Plan is
hereby amended, effective as of May 1, 1997, as follows:

amended by  increasing  from  2,100,000 to 2,800,000  Shares the total number of
Shares for which Options may be granted under the Plan.

     2. Except as  specifically  amended by this Fifth  Amendment,  the Plan, as
previously amended, shall remain in full force and effect and is hereby ratified
and confirmed.
