According to reports, Ralph Roberts, a cable industry leader who built Comcast, has died. He was 95 years old.

Roberts transformed Comcast from a small cable TV system in Mississippi into an entertainment and communications giant. According to Comcast, on Thursday, Roberts died in Philadelphia of natural causes.

Roberts started his career in his 40s when he stepped in the fledgling cable industry, with a $500,000 acquisition of American Cable Systems, a company with 1,200 subscribers in Tupelo, Mississippi. The name of the company was changed to Comcast by Roberts. He ran the company until he entered into 80s.

After that, one of his sons, Brian, who is now Comcast's chairman and CEO, was given the responsibility. However, he kept the title of chairman emeritus.

According to Steve Burke, CEO of NBCUniversal, who has worked at Comcast for 17 years, Roberts had great ambitions. He added that Ralph always used to think about development and things to be done in future. Burke added that he gave the control to his son Brian, who has been a determined person for the company.

At present, Comcast is the nation's largest provider of cable TV and home Internet service. It also owns NBCUniversal, home of the NBC network.

According to Terry Bienstock, a former general counsel at Comcast, "He remade the cable industry. When he started, it was a bunch of mom and pop businesses. He's shown that you can take that idea and transition it to a worldwide media business. The NBC thing will be his legacy".
