The newest version of MSN Messenger instant messaging product, released late Wednesday, allows consumers to download free backgrounds, pictures and other content tied to specific ad campaigns. The hope is that users will then share those downloads with other consumers — providing another boost to advertisers, who pay Microsoft for the privilege.

Interesting to see how this works out. I find it hard to force teenagers to follow a given plan so to speak. Trends usually happen from accident, but apparently Microsoft and other large companies feel they can get Messenger users to take on the brands of companies. Call me Mr. Trojan from now on then.

Microsoft also is releasing the official first version of MSN Spaces, a free personal Web journal system that debuted in test form in December. As part of an advertising campaign, Ford Motor Co.’s Volvo Cars of North America is debuting its own “space” that will solicit commentary from Volvo loyalists. Irving said Volvo will have editorial control of the posts.

I could care less.
