Line 10:
Note that 480p (640x480, progressive-scan) is '''not''' regarded as High Definition, but Enhanced Definition. Some PC monitor manufacturers bill a resolution of 2560x1600 (yes, it exists; [[Crack is Cheaper|no, it's not cheap]]) as "XHD".
Usually broadcasters tend to choose between 720p and 1080i depending on their type of programming; for instance [[American Broadcasting Company|ABC]], [[FOX]], [[ESPN]] and the A&E/Lifetime networks go with 720p to reduce image blur during fast motion in sporting events and films, and to address bandwidth concerns. 1080i broadcasters such as [[NBC]], [[CBS]], the Discovery networks and Food Network and HGTV go for image clarity. However in many cases the average consumer has no need to understand either format, as they all provide a great picture. 720p sets are cheaper than 1080i televisions, though as prices go down, 720p sets are becoming fewer and fewer. 1080p is mainly a media resolution utilized by camcorders, [[Blu-Ray]] and the [[Play Station 3]] as it is not currently possible to broadcast a 1080p signal over the air.
Despite the list below, basically '''everything''' new since 2009 on major networks and cable has been filmed in high definition television in North America. The few shows that haven't, such as ''America's Next Top Model'' and ''[[Big Brother]]'', have varying reasons, such as [[Appeal to Vanity|probable unease]] by Tyra Banks over the format, and in the case of ''Big Brother'' the high cost of refitting a show with multiple voyeuristic cameras with the HD variety (which are useless when most of your [[Hard Core]] fans watch on the web and accept low video quality), or have a budget so low they have to use old SD technology by default.
