As expected, Facebook has announced that they stop serving ads from Microsoft. While my friends over there had little to comment, except that they were just trying to get better control over their inventory, this comes as facebook has slowly been removing all ad networks from displaying ads. From insiders in the company, here are the reasons they are removing ad networks in general.

1)      Too many issues with ad quality. They’ve had more than one ad network, including one rightmedia network (go figure?) display flashy, annoying “you won” banners.

2)      Issues with slowness. Many of the ads and ad code was slowing down the pages, and with the new design, they felt this would not be plausible to allow just any ad network on their pages.

3)      Issues with trojans/takeovers. They had several instances where ad networks were inserting pops, takeovers and Trojans into the banners.
