Some discussion boards have some really long threads, but this is among the longest I've ever seen, at avsforum.com:

That link takes you to the beginning of the third continuation thread of the original topic, and there's a 4th continuation thread as well, that started on January 23.
In only the last two continuation threads of five total, there are currently 18,915 replies. There's a broken link, so I have no idea how many posts exist in the first three threads.
Unreal. The topic is over-the-air (OTA) digital television broadcasting for the Denver market. Special interest groups have litigated so long on this issue than Denver is now the only top 100 market in the USA without high-power digital broadcast capabilities. And though it "appears" that all the hurdles have been cleared, it may be at least another 12 to 24 months before that day actually arrives.
I don't know how many people are aware of this, but satellite digital signals are not broadcast at true HDTV levels, but they are interpolated into higher resolution at the receiver, resulting is a significant degradation from true HDTV levels, especially at 1080p by 1920 resolution. And many, if not most cable providers do the same thing in order to conserve bandwidth. They would rather ignore that fact though, because uninformed consumers make fewer demands for higher quality.
OTA high definition broadcasting IS broadcast at true HDTV levels, as mandated by the FCC. Some only broadcast at 720p by 1280, but most broadcast at 1080i by 1920. And some broadcast at the maximum 1920p by 1080 standard. (The "i" or "p" after the 1080 number stands for "interlaced" and "progressive". Progressive scan broadcasts are of higher quality than interlaced at the same resolution.)
