The developers of the popular online game Scrabulous have pulled the game from Facebook, after receiving legal threats from Hasbro. The game, which Hasbro claims is too closely related to its trademarked game Scrabble, will no longer be available to Facebook users in North America.
I wonder what this will do to the amount of time that users are spending on Facebook and how advertisers will respond. I know that I have personally spent many hours playing the game, while various ads sat in prime view on my dashboard.
