Current TV: Do you have it, what channel is it and what time is Olbermann on?

He's back, but what channel is he on again?

That's the question on the minds of those looking to check out Keith Olbermann's Current version of "Countdown," which makes its debut on Al Gore's cable channel tonight at 8:00 p.m. ET/7:00 p.m. CT. The show will also air in repeats at 11:00 p.m. and 2 a.m. ET.

Current is available in more than 60 million households in the U.S. on cable and satellite TV.

But do you get it?

If you live in New York or Los Angeles, chances are you do.

• On Time Warner Cable, Current is channel 103 in New York, and 142 in L.A.

• On Comcast, it's channel 107.

• On AT&T U-Verse, 189.

• Verizon FIOS, 192.

• Dish Network, 196.

If you have DirecTV, Current is channel 358 nationwide.

For those without DirecTV, you'll have to use the Current channel finder.

Outside the United States, Current is available in roughly 15 million homes. In the U.K. and Ireland, Current is on BSkyB (channel 183) and Virgin (channel 155); in Italy, it's on Sky Italia (channel 130).

If you don't have cable or satellite, your options for watching "Countdown" online, at least for the moment, are extremely limited.

According to a spokeswoman for the show, clips will be available on Current.com as well as iTunes, xfinitytv.com and Hulu sometime after the show airs, but full episodes will not because, as the FAQs state, "our agreements with our cable and satellite distributors do not allow us to do so."

Also of note: those TV viewers looking for Current TV HD are out of luck.

The channel is currently offered in standard-definition only. "We are actively working with out distributors to provide a high-definition channel in the near future," Current says.
