SUPPLEMENT TO THE PROSPECTUS
OF DEAN WITTER WORLD WIDE INVESTMENT TRUST
DATED JULY 28, 1997
On January 29, 1998, the Board of Trustees of Dean Witter World Wide
Investment Trust (the "Fund") approved an Agreement and Plan of Reorganization
by and between the Fund and Dean Witter Global Dividend Growth Securities ("Dean
Witter Global Dividend"), pursuant to which substantially all of the assets of
the Fund would be combined with those of Dean Witter Global Dividend and
shareholders of the Fund would become shareholders of Dean Witter Global
Dividend receiving shares of Dean Witter Global Dividend equal to the value of
their holdings in the Fund (the "Reorganization"). Each shareholder of the Fund
will receive the Class of shares of Dean Witter Global Dividend that corresponds
to the Class of shares of the Fund currently held by that shareholder. The
Reorganization is subject to the approval of shareholders of the Fund at a
special meeting of shareholders scheduled to be held on May 21, 1998. A proxy
statement formally detailing the proposal, the reasons for the Trustees' action,
and information concerning Dean Witter Global Dividend will be distributed to
shareholders of the Fund.
