Four months after firing Carol Bartz, Yahoo! Inc. has chosen Scott Thompson as its new CEO. Thompson, who will officially take office on January 9, was born in 1958 and has a technical background because he was president of PayPal but previously held roles connected to technological innovation in that company as well as in others such as Inovant, a Visa subsidiary.

Yahoo! Inc. announced it reached a definitive agreement to acquire online advertising solutions provider Interclick, Inc. for $9 per share for a total of about $270 million.

Yahoo! has fired Carol Bartz and Chief Financial Officer Tim Morse was named interim CEO. The terse message to her staff says: “I am very sad to tell you that I’ve just been fired over the phone by Yahoo’s Chairman of the Board. It has been my pleasure to work with all of you and I wish you only the best going forward.”.
