He came, he kinda sorta conquered and now he's left. Investor Carl Icahn, who stirred up investors during the Microsoft acquisition attempt, quit Yahoo!'s Board of Directors on Friday.
After Yahoo! failed to accept Microsoft's offer to fully acquire the Sunnyvale-based Internet company, Carl Icahn embarked on his own attempt to overthrow Yahoo!'s Board of Directors. Icahn ultimately settled with Yahoo! just before the 2008 shareholders meeting. He got a seat on the board plus the board was expanded to bring in some outsiders.
A few months later, Jerry Yang stepped down as CEO. Eventually, Carol Bartz was named as replacement. Now, there's a pending search deal with Microsoft, and Yahoo!'s stock has been steadily increasing.
Wam, Bam, Thank You Ma'am. I guess Icahn's work at Yahoo! is done.
