nullGoogle: The search giant foiled Microsoft once again. Microsoft CEO Steve Ballmer even pointed to a possible Google-Yahoo search ad agreement as big reason Microsoft walked away. Who knows whether a combined Yahoo-Microsoft would have provided Google with stiff competition, but Google for now has sidestepped that possibility.

nullCarl Icahn and Kirk Kerkorian: Seems like the 1980s all over again. (And yes, we have said that before). Icahn’s letter agreeing to backstop Blockbuster’s bid for Circuit City got the deal moving. Meanwhile, Kerkorian formally offered to buy up to 20 million of Ford’s shares.

nullCarphone Warehouse: Joint ventures can be tricky, but Carphone is hoping to hitch “a free ride” with Best Buy’s $2.15 billion investment, which increases the American retailer’s stake in the company’s cellphone retail unit to 50%, writes Damian Reece for the Daily Telegraph. Carphone is also expected to use the cash to expand its broadband business.

nullJerry Yang: Is there any CEO under more pressure? Chief Yahoo’s insistence on garnering $37 a share from Microsoft scuttled the deal and angered several large shareholders, notably Capital Research and Management’s Gordon Crawford.

nullKen Thompson: The longtime chairman and CEO of Wachovia got stripped of his chairman title. In the past few months, Wachovia has felt the brunt of its $26 billion purchase of Golden West Financial two years ago, which saddled the bank with dud mortgage assets.

nullMarius Kloppers: The Big Australian CEO’s bid for Rio Tinto, his first big move since taking the helm, increasingly seems to be slipping out of reach. This week Kloppers raised the possibility that a Chinese entity would take a stake in BHP — a move that could be seen as a challenge to the Rio deal.
