Comcast CEO Brian Roberts on Monday all but scoffed when a Wall Street Journal reporter asked him whether or not he was worried about Netflix's recent content deal with CBS.

The question gave Roberts the perfect opportunity to use what sounds like a well-prepared insult. "What used to be called 'reruns' on television is now called Netflix," he said. "We're not seeing it cut into our core business, but we are glad as a producer of content to see the value of that content rising."

Last week, Netflix announced a deal to add old CBS shows to its "Watch Instantly" library. In December, Netflix also expanded its "Watch Instantly" content partnership with ABC.

In January Comcast finalized the multi-billion dollar acquisition of NBC Universal, but was barred by the Federal Communications Commission from taking managerial control of Hulu, an ad-based video-on-demand platform that also airs content from competing networks and is part-owned by NBC Universal.

Meanwhile Comcast is beefing up content on "TV Everywhere" Xfinity TV service, which allows subscribers to watch Comcast content online. Earlier this month the Internet provider struck a deal with Time Warner to allow Web-based access to shows from TNT, TBS, CNN, HLN, Cartoon Network, and more shortly after they air on TV.

Later in the interview, Roberts reiterated his stance that Comcast's bottom line will benefit as both a content producer and broadband provider.

"I have believed and said for a long time that more video on the Internet is more friend than foe. I think our broadband business is doing so well because we give the best Internet experience, residentially, in this country," he said.
