Former FCC Chair: Need to ensure certainty in market

FCC's obligation to ensure certainty: Genachoswki

Former Federal Communications Commission Chair Julius Genachowski said on Wednesday that the agency's job is to ensure certainty in the market.

"I think the FCC has the responsibility to make sure there is certainty and predictability in the marketplace so that deals that should get done, get done, and where it's necessary deals that shouldn't get done, not a lot of time is spent on them," Genachowski told CNBC's "Power Lunch."

Genachowski spoke to CNBC in an interview from the Code Conference in Rancho Palos Verdes, California. He is currently managing director at The Carlyle Group.

"They [FCC] seemed to have looked at the Comcast-Time Warner Cable deal and said that if you combine those two companies, they would reach a very significant percentage of the country's broadband customers, over 60 percent, and that they said was just too much."

He said that the FCC is very serious about promoting competition as "a main driver of innovation and investment."
