The story started in December 2004, when Electronic Arts acquired a 20-percent block of Ubisoft Entertainment in what was considered a hostile action. EA's disappointing quarter results gave some hope to the Ubisoft founders in the next year. However, on Friday EA increased its holding of voting shares to 24.86%. There are more details and a good analysis at IGN:

"They own the same number of shares - it's just that the shares they own have more substantial voting rights," Sebastian said. "I still don't think that's enough to bring about a change of control. In the past, Ubisoft officials have publicly said they have a number of options for the future of the company - including joining forces with a large media company, partnering with a publisher like EA or remaining independent."
