Must be a good thing for Martha

Martha Stewart is heading to cable.

The lifestyle queen has signed a deal to move her daily program to the Hallmark Channel, effective this September.

“The Martha Stewart Show” is currently syndicated to broadcast channels across the country.

After Stewart’s show, Hallmark will air 90 minutes of programming created by her production company.

Stewart’s move echoes that of fellow daytime star Oprah Winfrey, who is leaving her syndicated show next year and will set up shop at a network created for her by Discovery Communications.

Are they really serious?

Clear Channel Communications says it’s interested in signing Howard Stern when the shock jock’s contract with Sirius satellite radio expires.

That would mark an about-face for the nation’s largest radio chain, which yanked Stern’s show from its stations in 2004 after his raunchy broadcasts were repeatedly subjected to regulatory fines.

Stern, whose five-year, $500 million contract with Sirius XM Radio expires at year’s end, does not face the same restrictions with Sirius because that show is distributed over satellite radio.

“I can’t imagine the day where I would ever work for Clear Channel. That’s pretty sure,” said Stern, who has said on his show that he might retire once his contract expires.
