BARCELONA—Microsoft could buy a stake in YouTube competitor Dailymotion, Stéphane Richard, CEO of Orange, said at Mobile World Congress in Barcelona today. The video streaming site is currently wholly owned by the French telecom giant.

Richard said that while no agreement had been made yet, he is "confident" that the companies could come to some arrangement. Whatever the terms may be, Orange will retain a majority stake in the company.

Similar talks between Dailymotion and Yahoo fell through last year. The search and advertising firm wanted to buy a 75 percent stake for $200 million, but the French government, which owns 27 percent of Orange, derailed the deal.

Orange, however, still sought investment from other companies, wanting both to reduce its stake and improve Dailymotion's international appeal.

Should the plans come to fruition, this will not be the first time that Microsoft has had a piece of the online video pie. It shuttered its YouTube-like MSN Soapbox video service in 2009 after saying that it was a poor fit for the 2009 economic climate.
