Kent helmed the owner of CNN, TBS, TNT, Cartoon Network and Turner Classic Movies since 2003.

TW CEO Jeff Bewkes wrote a memo to praise Kent for leading Turner "through a period of rapid change with an unwavering focus on both driving the business forward and making sure that Turner remains a place that nurtures and rewards talent."

Martin is a former Wall Street analyst who joined TW five years ago.

He had been in charge of accounting, finances, mergers and acquisitions.
