AOL has tapped Susan Lyne, one of its board members and the former president of ABC Entertainment, as chief executive of its global Brand Group.

Lyne, who also ran Martha Steward Living Omnimedia and most recently online retailer Gilt Groupe, will oversee all aspects of the brand growth strategy, including increasing traffic across properties, partnerships with advertisers and publishers and attracting top talent, with a particular focus on content, design, programming and product.

“Susan has a proven track record of brand building and aggressive growth,” said AOL topper Tim Armstrong. “I know she’ll bring that same drive and growth-oriented mentality to our Brand Group. AOL ended 2012 growing revenue for the first time in eight years, and we expect Susan to help build on this momentum and take our brands to the next level.”

Lyne said that in “three years as an AOL board member, I have partnered with Tim Armstrong and my fellow directors to help drive the company’s transformation, and have seen AOL make great strides as it continues to innovate, grow and evolve.”

Lyne will remain vice chairman of Gilt.

As ABC Entertainment prexy, she oversaw the development of “Desperate Housewives,” “Lost” and “Grey’s Anatomy.”
