Microsoft opens Office 365- This week, Microsoft released  a cloud-based version of its Microsoft Office suite to the public for beta testing called Office 365.

Yahoo’s revenue nightmare- On Monday, Yahoo released  its Q1 revenue report, which revealed significant declines in Yahoo’s search revenue. Yahoo is blaming its partner Microsoft for the 6 percent year over year decline in revenue. According to a press release issued on Monday, “[The decline was] primarily due to the required change in revenue presentation related to the Search Agreement and the associated revenue share with Microsoft. For transitioned markets (U.S. and Canada), Yahoo! now reports revenue associated with the Search Agreement on a net (after TAC) basis rather than a gross basis. Excluding the impact of these two items and the impact of the divestitures of Zimbra and HotJobs, broadband deferred revenue amortization, and certain fee rate reductions, revenue for the first quarter of 2011 decreased 8 percent compared to the first quarter of 2010.” Blaming their troubles on Microsoft won’t cut it long term, however. As Danny Sullivan  wrote on Tuesday in a response to Yahoo’s announcement, “But even without these factors, Yahoo has seen an almost unbroken quarterly decline in search revenues since 2008. Failure is not all down to Microsoft.” eBay to purchase Where.com- eBay has reportedly  acquired Boston-based hyperlocal media company, Where.com , for $135 million.
