Randall Rothenberg has been named executive vice president, chief digital officer of Time Inc., a new post.

Starting in January, he is responsible for developing Time Inc's digital growth strategy, as well as coordinating its editorial, tech, marketing and advertising efforts. Rothenberg is charged with building the company's interactive brand portfolio and finding new digital revenue streams. In addition, he will establish a virtual Center for Digital Innovation within Time Inc. to fund projects.

Previously, he was president/CEO of the Interactive Advertising Bureau. During his three-year tenure, the IAB's membership increased by 50% to 460 companies and revenues more than doubled.

Jack Griffin, CEO of Time Inc., said Rothenberg has participated "in every aspect of the digital media marketplace -- from content creation to marketing to revenue -- giving him a unique perspective." He will report to Griffin.

Prior to IAB, Rothenberg also worked for Booz Allen Hamilton, where he oversaw business development, and The New York Times as technology editor and politics editor for the Sunday magazine and a media and marketing reporter.

The Time Inc. sites attract more than 50 million unique visitors each month and serve nearly 2 billion page views. Time Inc. brands have built an audience of more than 15 million on Facebook and Twitter.

Separately, IAB is searching for a new CEO. Patrick Dolan, its EVP/ COO, will be acting as the organization's leader until an official appointment is made. David Doty, also recently promoted to senior vice president and chief marketing officer, will join Dolan in running the organization.
