Well this is new

"WASHINGTON (AP) — Too busy playing video games to watch presidential ads on television? Barack Obama has found you, too, by becoming the first presidential candidate to buy ad space inside a game.

Eighteen video games, including the extremely popular "Guitar Hero" and "Madden 09," will feature in-game ads from the Obama campaign in the final weeks before the election. The ads — appearing on billboards and other signage — remind players that early voting has begun and plug a campaign Web site that encourages people to register for early voting.

Obama campaign officials said the video game ads target 10 states that allow early voting, including several battleground states: Ohio, Iowa, Indiana, Montana, Wisconsin, North Carolina, Nevada, New Mexico, Florida, and Colorado."

All this advertising combined with his media buy makes me really curious about just how much money Obama has raised. $100M this month? It seems possible. (edit: apparently the Washington Post had the exact same thought)
