CBS CORPORATION AND BIG ENTERTAINMENT SIGN DEFINITIVE
                 AGREEMENT FOR EXPANSION OF PREVIOUSLY ANNOUNCED
                        RELATIONSHIP WITH HOLLYWOOD.COM

              CBS TO RECEIVE 30% EQUITY STAKE IN BIG ENTERTAINMENT

  BIG ENTERTAINMENT TO RECEIVE $105 MILLION OF ADVERTISING, PROMOTION, CONTENT
                             AND OTHER CONSIDERATION

                       HOLLYWOOD.COM TO BE PROMOTED ON CBS


           NEW YORK, NY and BOCA RATON, FL, September 1, 1999 -- CBS Corporation
(NYSE:CBS) and Big Entertainment, Inc. (NASDAQ:BIGE) today announced that they
have signed a definitive agreement, expanding on the relationship the two
companies first announced in April.

           Under the terms of the agreement, CBS will receive an approximately
30% ownership interest in Big Entertainment, which includes Big Entertainment's
Hollywood.com and Big's entertainment properties. At the same time, Big will
receive approximately $105 million in advertising, promotion, content and other
consideration, over a term of seven years. Advertising and promotion will take
place across the full range of CBS properties, including television, radio and
outdoor. Infinity Broadcasting Corporation (NYSE: INF), a majority-owned
subsidiary of CBS Corporation, will receive a pro rata interest in the
investment.

           Additionally, CBS will receive a warrant to purchase an additional
five percent interest in Big Entertainment. CBS Corporation will hold three
seats on Big's Board of Directors.

           The agreement provides for a broader transaction than originally
announced by the parties on April 12, 1999 -- CBS's investment will now be made
directly in Big Entertainment rather than in a subsidiary of Big Entertainment.
The revised agreement adjusts CBS's consideration and equity stake to reflect
the additional agreed-upon value in Big's overall businesses.

           "By joining forces with CBS, and harnessing their powerhouse of
promotional and advertising strengths to promote and brand Hollywood.com, we
anticipate that Hollywood.com will quickly become one of the most recognized
names on the Internet," said Mitchell Rubenstein, Chairman and Chief Executive
Officer, Big Entertainment. "We welcome CBS to our family of strategic
shareholders, which includes Gannett and Times Mirror."

           Wasserstein Perella & Co., Inc. initiated this transaction and acted
as financial advisor to Big Entertainment.

           Completion of this transaction is subject to approval by the
shareholders of Big Entertainment. The two companies plan for CBS's promotion of
Hollywood.com to commence during the fall television season.

           Big Entertainment, Inc. was founded by Mitchell Rubenstein and Laurie
S. Silvers, who earlier founded the Sci-Fi Channel(TM). Big Entertainment owns
Hollywood.com, bigE.com, and CinemaSource, a combination of movie-related
Internet businesses that are being combined under the "Hollywood.com" brand. Big
Entertainment has entered into a definitive agreement to acquire pkbaseline.com,
a comprehensive online film database. Big Entertainment also owns entertainment
properties created for it by best-selling authors and media celebrities,
including Leonard Nimoy and Mickey Spillane.

           Hollywood.com (www.hollywood.com) is a premier website for movies.
