When WWTBAM exploded onto American TV screens in 1999, it inspired the same kind of merchandising craze previously seen only by long-running, established hits like Jeopardy! and Wheel of Fortune.  We can't possibly list every trinket and T-shirt offered for sale, but here are the games:
 

        (Pressman 2000) Two editions, plus a Junior Edition
 

        (Disney 1999) Three editions [Regis Philbin on cover], a Sports Edition and a Kids Edition
In 2001, the first two regular editions were packaged with the Sports Edition and released together under the title Platinum Edition.
 

        (Disney 2000) for Sony Playstation [Regis Philbin on cover]
            Two editions, named Second Edition and Third Edition
        (Disney 2000) for Nintendo Game Boy Color [Regis Philbin on cover]
            One edition, named Second Edition
There were no console games based on the First Edition CD-ROM.
 

        (Hyperion 1999) Who Wants to Be a Millionaire
            [Regis Philbin on cover] Foreword by Executive Producer Michael P. Davies
"The Official Book From the Hit TV Show" offers sample questions and behind-the-scenes tidbits.
        (Monkey Boy 2001) Millionaire Boy: The Adventures of a Game Show Contestant by J.E. Matzer
Matzer was a hot seat winner early in the show's run and wrote this unauthorized personal account of his experiences.
        (Berkley 2002) Matching Wits With The Million Dollar Mind by John Carpenter and Rod L. Evans
            [Carpenter on cover]
Carpenter was the first million dollar winner, and he extends his small window of fame with this unauthorized quiz book.
 

        (Tiger 2000) Three versions
Tiger released a traditional hand-held game, a larger tabletop version and a tiny keychain version of WWTBAM.

        (Imagination 2007) [Meredith Vierra on cover] COMING SOON
 

        Who Wants to Be a Millionaire: The Album (2000)
The American soundtrack album contains pop and rock standards inspired by the series, as well as actual segments from the program.  A British import disc also released in 2000 contained nothing but music used on the series (virtually interchangeable with the American version of the show).
