In 4 Days

Microsoft's $300 million ad campaign staring king of comedy Jerry Seinfeld, and other comedians, including Will Ferrell and Chris Rock.

The software giant is providing few details on the campaign, but it appears that Mr. Seinfeld will receive $10 million for his participation, according to The Wall Street Journal. He is expected to appear next to former CEO Bill Gates and say something along the lines of “Windows, Not Walls.”

The campaign, to be aired September 4 nationwide, is the largest in the company’s history and amounts to three-quarter of its total advertising budget in 2007.
