Chief Operating Officer John Billock a longtime HBO executive; President Tom Baxter; and Chief Marketing Officer Chuck Ellis are leaving the cable provider. CEO Glenn Britt remains in place.
A call for comment to Mr. Ellis was not returned by deadline.
According to internal company documents obtained by AdAge.com, the company is already searching for a new No. 2 executive to Mr. Britt and a new marketing chief.
Mr. Ellis, an 18-year veteran of Time Warner's cable operations, was named marketing chief in October 2002. After conducting a review of agencies that included Interpublic Group of Cos.' Deutsch and Publicis Groupe's Fallon and Leo Burnett USA, Mr. Ellis named WPP Group's Ogilvy & Mather, New York, as the winner of its $65 million advertising account.
The cable giant also works with independent agency Shepardson, Stern & Kaminsky, New York, on strategic assignments. Mr. Ellis' resignation raises the possibility of a fresh agency review.
Seek greater efficiencies
One executive familiar with the situation said parent Time Warner's chairman of its media and communications group, Don Logan, and Mr. Britt had very clear ideas about the need to gain greater efficiencies and simplify the structure of the traditionally Byzantine business.
This executive also said the company might look to centralize more of its business operations. Time Warner Cable is currently in talks with Sprint to offer trial cell phone service for its customers. The cable company has 11 million subscribers in 27 states and is second only to Comcast in size.
A spokesman for Time Warner Cable denied reports that the changes were part of recommendations made by management consultant McKinsey & Co.
