And not much of anyone else either.   Broadcast TV (read the big networks) are either 720p or 1080i (from the source, so Comcast etc. have no choice but to pass through the original resolution).  Likewise with most "cable channels".  Direct TV I believe offers a limited amount of 1080p.  The only consistent source of 1080p is Blue-Ray.   Hence, I didn't waste my bucks on a 1080p TV.  I have no interest in purchasing DVD's for movies that I watch exactly once and video on demand rental and purchase sources are rarely 1080p.

yes, this is correct, no one is "broadcasting" in 1080p because there aren't any networks that film in 1080p *yet*


1080p broadcasting will probably not be done on a large scale, from what i understand this is expensive, and eats excessive amounts of bandwidth.

From wikipedia via Google search on 1080p




In the United States, 1080p over-the-air broadcasts still do not exist as of 2010; all major networks use either 720p60 or 1080i60 encoded with MPEG-2. However, satellite service has many channels that utilize the 1080p/24-30 format with MPEG-4 AVC/H.264 encoding (e.g. DirecTV, XstreamHD, and Dish Network).

For material that originated from a progressive scanned 24 frame/s source (such as film), MPEG-2 allows the video to be coded as 1080p24, irrespective of the final output format; these progressively-coded frames are tagged with metadata (literally, fields of the PICTURE header) instructing a decoder how to perform a 3:2 pulldown to interlace them. While the formal output of the MPEG-2 decoding process from such stations is 1080i60, the actual content is coded as 1080p24 and can be viewed as such, using a process known as inverse telecine, since no information is lost even when the broadcaster (as opposed to the receiver) performs the 3:2 pulldown.[11]

 Blu-ray Disc

Blu-ray Discs are able to hold 1080p HD content, and most movies released on Blu-ray Disc produce a full 1080p HD picture when the player is connected to a 1080p HDTV with an HDMI cable. However, the Blu-ray Disc video specification only allows encoding of 1080p24 signal, and not 1080p50 or 1080p60.[
