Microsoft is on the verge of investing in the company’s largest and most expensive advertising campaign ever. This is a promotion for Windows Vista and a response to Apple’s famous campaign with a human PC and a human Mac that succeeded in promoting Mac’s beautiful, functional, and fun technology. Those ads, created by Omnicom Group Inc.'s TBWA/Chiat/Day, feature a nerdy PC guy getting upstaged by a hip Mac counterpart.

So Microsoft chose Jerry Seinfeld to get them out of the fog along with Michel Gondry, the director of “The Eternal Sunshine of the Spotless Mind.” Seinfeld will appear with Microsoft Chairman Bill Gates in ads and receive about $10 million for the work, or so they say. The campaign is said to debut Sept. 4 and it cost them $300 million according to the Wall Street Journal.

It appears that Microsoft’s new slogan will be “Windows, Not Walls,” and Gondry will bring a great deal of his power of imagination to the campaign for sure. Locations including the Brooklyn Public Library, Prospect Park and parts of the neighborhood of Carroll Gardens were closed down in July so that the French director could shoot the commercials.

Microsoft's immediate goal is to reverse the negative public perception of Windows Vista, the latest version of the company's personal-computer operating system.

It is believed that other comedians will join Seinfeld in this campaign such as Chris Rock and Will Ferrell.

Everybody is eager to find out how the target public will react to Jerry Seinfeld as it has been a while since his popularity was on its highest peaks. He is 54 years old now.
