Comcast Promotes Marcien Jenckes to President, Advertising

Comcast Cable has promoted Marcien Jenckes to president, advertising, where he now heads up all of the company’s advertising assets and businesses, including Comcast Spotlight.

Word of Jenckes’s new role at Comcast has been circulating for weeks, but is now confirmed by his updated bio on Comcast’s corporate web site.

Jenckes most recently was EVP, consumer services at Comcast Cable, where he oversaw the company’s video, Internet, voice, and Xfinity Home businesses. Comcast has not named a permanent replacement for Jenckes’s prior role.

In his new role, Jenckes’s leadership on the advertising side of the house expands broadly.

Last year, as part of an operational reorg, Jenckes took over Comcast’s ad-tech operations, which have been expanding following the company’s buying spree in the sector in recent years that included the acquisitions of companies such as FreeWheel,, Visible World, This Technology, and Strata, a company that powers more than 1,200 media buying agencies and in-house advertisers.

Jenckes now also runs Comcast Spotlight, the unit focused on local, regional and national spot-advertising.

Charlie Thurston, the former president for Comcast Spotlight, has stepped away from the day-to-day running of that division, but is still serving Comcast in an advisory role, industry sources said.

Prior to joining Comcast, Marcien was with digital ad and media syndication startups such as Grab Networks and Voxant, and is also late of AOL and McKinsey & Company. He holds a MBA from the Darden School at the University of Virginia, and a BA in economics and political science from New York University.
