Some more information: you must be careful when seeing a spec for a TV because you have to consider two things: the source and the display. All HDTV sets will accept the 720p and 1080i standards; but they display only one. All fixed-pixel sets (with one exception) display in progressive mode only, regardless of the input. So if you buy a DLP or LCD TV that displays 1080p, you are watching a picture that has been converted from 1080i to 1080p inside the set. The converted signal is never as good as one that originates as 1080p, and conversion (de-interlacing) quality may not alway be the best.
As was pointed out, there are no broadcasts in 1080p--they are either 1080i or 720p. However, the new high definition DVD players (HD-DVD and Blu-Ray) will provide a true 1080p signal. BUT!! that's not enough. If you are interested in that, you have to make sure the 1080p set actually ACCEPTS 1080p signals as input. In fact, most do not, but the newer sets are beginning to have it. (Some video games also output a 1080p signal). One can hope that eventually 1080i will disappear, and we won't have to worry about the difference.

The i and p stands for "interlaced" and "progressive scan". Interlaced means that the picture is created in two passes (540 lines for each pass), drawing only every second line of the image but still giving the illusion of full motion. The progressive scan is considered a better quality as it re-draws the entire screen (1080 lines) in one pass.

Good answer above. Presently, there are no stations brodcasting in 1080P anywhere that I am aware of.
