Nine video games from Electronic Arts Inc., ranging from the extremely popular "Madden 09" football game to the street racing "Burnout: Paradise," feature in-game ads from the Obama campaign. The ads -- they appear on billboards and other signage -- remind players that early voting has begun and plug a campaign Web site. The idea of embedding advertising temporarily inside a video game is relatively new, having only begun about 18 months ago, and Obama is the first presidential candidate to buy space, company officials said.
