Yahoo Chairman Bostock Steps Down

Yahoo has shaken up its board, and chairman Roy Bostock is on the list of directors stepping down. He'll exit along with independent directors Vyomesh Joshi, Arthur Kern, and Gary Wilson. Replacing them are newly elected directors former Rovio CEO Alfred Amoroso and Maynard Webb, chairman of LiveOps.

The changes follow the departure last month of Jerry Yang. Yang resigned his seat on the board and other official roles with the company.

Bostock, who handled the firing of previous CEO Carol Bartz last fall, wrote in a letter, "I have every expectation that under [new CEO Scott Thompson's] leadership, working together with the reconstituted board, the Company will thrive for many years to come."

The search is still on for more independent directors, Bostock said in the letter.
