Oprah Winfrey led the way, showing broadcasters how to use Skype video calling on network TV.
A few have been quick to follow.

From the get-go, Jimmy Fallon, former Saturday Night Live comedian and now host of NBC's Late Night with Jimmy Fallon, promised to integrate tech into his show, including Skype.

This week, he featured director Jon Favreau, who talked from Canada on Skype video about the much-anticipated Ironman 2 due out next year.

The director had twittered a heads-up to fans: "I'll be skyping a bit from the set of Iron Man tonite on Jimmy Fallon."

But during the interview, Favreau actually didn't show his hand--other than teasing viewers with a glimpse at a bionic hand. He said he was Robert Downey Jr.'s "stunt hand."

He joked that Marvel comics had been on his case for twittering too much from his set.

Over at the FOX News Channel, Greta Van Susteren, host of On the Record at 10 p.m. ET weeknights, tells her fans they can "interact with Greta directly here on her blog - post a comment, follow her on Twitter, or chat with her on Skype -- her screenname is GretaWire."

Stay tuned to see the next Skype development.
