As found in the Wall Street Journal, Microsoft has brought comedian Jerry Seinfeld aboard its $300 million ad campaign, which is being put together in an attempt to change the people’s perspective on its Windows Vista operating system.

The theme of the campaign will be "Windows not Walls," the Wall Street Journal reported Thursday and will focus on "breaking down barriers that prevent people and ideas from connecting."

According to the publication, Jerry Seinfeld is to receive no less than $10 million for his efforts and the results of the collaboration will be presented to the public on September 4th.

With the upcoming ads, Microsoft will be trying to shake off the image that its Vista has been given by Apple’s campaign. In the clip series, while Vista was personified into a boring, middle aged office type, Apple's Leopard OS was presented as a very cool young man. The ads proved to be quite effective and managed to increase Leopard sales.

A lot of businesses chose not to upgrade from Windows XP to Vista, mentioning reasons such as high costs or compatibility issues; instead, some said they would wait for the release of Microsoft’s Windows 7, which is expected to change everything.
Until this happens however, Microsoft will be going through some difficult times, as its market share is constantly dropping. Besides Leopard, the open source Linux OS is also attracting more and more users.

Vista was introduced in January 2007 and quickly became the world's dominant operating system since it is pre-installed on the vast majority of new PCs. But it has failed to catch on in the business market and according to a recent report many PC owners often downgrade their system to run the previous operating system Windows XP, which is considered by many experts to be faster and more stable.

While going through Microsoft and Gartner information, it was found that Microsoft’s market share dropped from 67% in 2002 (with Windows XP) to 39% in 2007 (with Vista).

The upcoming ad campaign was thought out by the Miami based Crispin, Porter + Bogusky agency.
