- T-R-O-U-B-L-E could loom for a Scrabble knockoff that has become one of the most popular activities on Facebook.
Hasbro Inc., the company that owns the word game's North American rights, sued the creators of the Scrabulous program on Thursday, less than two weeks after the release of an authorized version of Scrabble for Facebook.
Hasbro said in its lawsuit that Scrabulous violates its copyright and trademarks. Separately, Hasbro asked Facebook to block the game.
In the year since Facebook began letting outside developers write Web programs that Facebook members can plug into their personal profile pages, Scrabulous has attracted some half-million daily users, despite efforts by Scrabble's owners to end it.
