Kathy SavittYahoo CMO Kathy Savitt—one of CEO Marissa Mayer’s first hires when Mayer took charge in 2012—is leaving the company to become president of digital at STX Entertainment.

Savitt will oversee all of STX’s global digital strategy and report to CEO Robert Simonds.

In addition to being CMO, Savitt recently took on the role of head of media, where she has overseen the launch of Yahoo Tumblr-supported digital magazines and the creation of Yahoo original programming for video streaming services Screen, the Hollywood Reporter said.

Savitt’s departure comes on the heels of other high-profile exits from Yahoo, which continues to struggle mightily against Web rivals such as Google and Facebook.

According to re/code, Scott Burke, Yahoo’s senior VP advertising and data platforms, left quietly in August after losing much of his portfolio to other execs, and Dawn Airey, who headed Europe and other international units for the company, just left after two years at Yahoo because she was frustrated by a lack of progress at Yahoo.

Yahoo’s stock price continues to hover in the $30-range.
