One of the hooks Microsoft has used to get developers to build apps for Windows 8 and Windows Phone 8 has been pubCenter, an ad network that's easy to add to apps and provides revenue back to publishers. But many developers found that on April 1 that revenue abruptly dropped by an order of magnitude, with most potential ad impressions going unsold; one developer reported only 160,000 ads served to 60 million requests, a fill rate of less than 0.3%. Since many of the ads before April 1 had been for Bing, this may be a sign that Microsoft is no longer willing to subsidize its developers — and that advertisers aren't that interested in buying ads in Windows 8 apps."
