Yahoo has been trying to revamp itself for the better part of 18 months, ever since Carol Bartz became CEO. The hope was to bring in a tough new leader which will provide a vision and a plan for moving Yahoo forward again.

But things aren't going very well as the company is now reportedly losing another three top execs after a constant string of departures.

All Things D reports that Yahoo US head Hilary Schneider, US Audience head David Ko and VP of Media Jimmy Pitaro are all leaving for greener pastures.

The official announcement will be made on Friday, after the market closes, apparently, to try to minimize the damage the news will have on the already ailing Yahoo stock.

The report says that, even though Yahoo will try to spin this as an ouster or, yet another, reorganization, the three left on their own account having been dissatisfied with conditions at the internet company.

A large number of high-level execs have been leaving Yahoo in recent months. While the company, Bartz in particular, has been saying that this is normal or even that this is all part of the plan, more and more people are saying that Bartz's job may be in danger.

In fact, members of the board apparently met this week to discuss future strategy. The plan, apparently, is to hire a strong number two to serve under Bartz and eventually replace her, perhaps once her contract expires another year and a half from now.

One thing is for sure, things are not looking good at Yahoo. Stock price has been stale and most people have lost faith in the company as a tech leader.

Bartz was brought in precisely to shake things up, but so far hasn't managed to impress Wall Street. What's more, while, officially, Yahoo is transforming itself into a media company, it hasn't been able to put forward a credible vision.
