Carl Bialik from the WSJ writes "'Advertising in videogames, dominated in the past by static ads such as billboards and signposts, is beginning to look more like TV commercials,' according to the Wall Street Journal. Massive, the company that brought still ads to videogames last year, is now introducing full-motion ads to PC-based games (not yet console titles). Massive CEO Mitchell Davis 'says Hollywood movie studios have shown particular interest in running 15-second movie trailers in online games.' Also of note: 'One problem with the full-motion ads is that gamers can easily avoid watching them. The full-motion ads start playing when a player moves near the ad spot on the screen -- and stop playing when the player moves away. As a result, gamers may see only a few seconds of the 15-second ads. Massive says it won't charge advertisers unless the full ad has been viewed.'"
