Steve Berkowitz is still listed as the chief executive of IAC Search and Media. Better change that soon.

Microsoft said this afternoon that it has hired Berkowitz as a senior vice president in its Platforms and Services Division, replacing David Cole, who will begin his leave of absence in May. Before moving into his position at IAC Search & Media, a unit of IAC/InterActiveCorp., he was president of Ask.com, one of IAC's more well-known Web properties (it used to be known as AskJeeves). He has also been president of IDG Books, which published the "Dummies" series. Berkowitz starts on May 8.

According to Microsoft, Berkowitz will run a group that includes MSN.com, MSNTV and MSN Internet Access programming, advertising sales, business development, and marketing for Live Platforms, MSN and Windows Live.
