Former Time Warner Cable Chairman and CEO Glenn Britt died Wednesday at his New York City home. He was 65 and had been fighting cancer.

Britt retired from the cable giant at the end of last year. In October, he told employees that his cancer had returned. He had previously been treated for melanoma and his retirement had been planned before receiving his diagnosis.

“Glenn left us with a legacy of innovation, integrity and inclusion,” Rob Marcus, Time Warner Cable Chairman & CEO, said in a statement. “We were guided for many years by his strong belief that a company must be willing to reinvent itself to be successful.”

Reinvention was often the theme of Britt’s tenure, as the veteran executive oversaw Time Warner Cable at a time of challenge and change for the pay TV landscape. He is credited with helping to launch Time Warner’s Road Runner internet service, overseeing its move into telecom, and guiding the newly independent company following its 2009 spinoff from Time Warner Inc.

Cognizant of the threats that online video posed to cable subscription, Britt pushed Time Warner Cable to expand and enhance its broadband offerings.

In February, Comcast announced that it planned to purchase Time Warner Cable for $45.2 billion. The deal is still awaiting regulatory approval.

Comcast Chairman and CEO Brian L. Roberts honored Britt’s philanthropy and competitive spirit in a statement Wednesday.

“Glenn Britt was an incredible leader, visionary, and for decades he was a wonderful friend and mentor,” Roberts said. “He was a key part of our industry’s growth and success and was a true leader in every respect.”

Britt was a company veteran, having joined Time Inc. more than forty years ago, in 1972. He rose up the corporate ladder, becoming vice president of Time Inc. in 1986, treasurer in 1986 and vice president-finance in 1988.

He later was named senior vice president and treasurer of Time Warner Inc. and then president and CEO of Time Warner Cable Ventures.

He was named CEO of Time Warner Cable in 2001 and chairman of its board in 2009.
