Yahoo chief executive Carol Bartz is facing crisis as internet giant’s three top executives are departing to try their luck elsewhere.

The departing executives are: Hilary Schneider, David Ko and Jimmy Pitaro. Hilary Schneider was in-charge of Yahoo's advertising in the US; David Ko was responsible for mobile and audience; while Jimmy Pitaro was running the division that created the heavily trafficked sports, news and finance sections of Yahoo's website.

The technology site All Things Digital was the first to disclose the departures. Yahoo confirmed that report on Thursday.

The departures is a big jolt for Carol Bartz, known for her brash and sacrilegious language, who has been making hard efforts to cut costs while looking to find ways to get Internet users to spend more and more time on Yahoo's website.

Commenting on the departures, Bartz wrote in an email, "We have a good plan in place. In fact, I’m more fired up than ever and can roll with the punches.”

Earlier, sixty-two-year-old Bartz warned it could take many years to revive Yahoo. She pointed out that Apple did not become a Wall Street darling until Steve Jobs returned to it in 1997.

Yahoo has seen its market share slumped drastically. Social networking platforms such as Twitter and Facebook also hit Yahoo hard.

Yahoo's stock price has already slipped by around 15 per cent so far this year, leaving it even below the $33 per share that Microsoft was offering to acquire the entire company in May 2008.
