See Beyond Geography's post of NYT, Obama’s War Chest Drives a 50-State Strategy:
http://www.democraticunderground.com/discuss/duboard.php?az=view_all&address=132x6394905Beyond the "War Chest" of money, the article points out that the Obama campaign builds on the work of Howard Dean -- and both the Bush campaign, and Harold Ickes:
"The campaign is in many ways building on a strategy championed by Howard Dean, the party chairman who has been pressing Democrats to build a presence in all states rather than focus primarily on battlegrounds....

Obama campaign officials said that is because they are considering a specially tailored commercial campaign on niche cable networks like MTV, with its young audience, or BET, with an African-American viewership Mr. Obama’s aides consider crucial for victory.
“It’s a great opportunity to get people information that may be particularly germane to them,” David Axelrod, the campaign’s chief strategist said of the specialty cable commercials, first perfected by Mr. Bush in 2004. Yet Mr. Obama’s team has looked into advertising in as many as 25 states and has made clear its openness to running ads on the broadcast television networks....
