Comcast Chief Financial Officer Michael Angelakis told an investor conference that the company had "very modest expectations for this fall" for NBC’s new prime-time season, according to The Hollywood Reporter.

He also expressed faith in new NBC Entertainment chief Bob Greenblatt, saying, "This fall does not have his stamp on it," because the shows were already in development when he came to NBC, the story says.

"He has the ball, and we have to be patient," Angelakis said at the Wells Fargo Securities 2011 Technology, Media & Telecom Conference on Tuesday, according to the story.

Angelakis said the company remains optimistic about a turnaround for the network, which has been deeply mired in fourth place among the four major broadcast networks. He said NBC represents “a huge opportunity,” but added: “We have a lot of upside, but it will take a lot of time,” the story reports.
