This coming Friday, the 12th of June, the US will be entering an age of digital brilliance which has been long overdue. I was just wondering, how many people haven't switched over yet in the US here and if your in another country if you have and how was the experience?? Did the gov't help you out which in turn came straight out of another program you had to help pay for? Also for everyone in the world...how many TVs in your house are HD ready and how many aren't??
Lets see, 4 TVs in our house are HD ready, one is not. My little TV in my PC room right next to me now is not HD. In the US here, we were supposed to switch over in February and now its this June. Also here is a little brief history on the early days of HD:

The term high definition once described a series of television systems originating from the late 1930s, however, these systems were only "high definition" when compared to earlier systems that were based on mechanical systems with as few as 30 lines of resolution.
The British high definition TV service started trials in August 1936 and a regular service in November 1936 using both the Baird 240 line and Marconi-EMI 405 line systems. The Baird system was discontinued in February 1937. In 1938 France followed with their own 441 line system, which was also used by a number of other countries. The US NTSC system joined in 1939. In 1949 France introduced an even higher resolution standard at 819 lines, a system that would be high definition even by today's standards, but it was monochrome only. All of these systems used interlacing and a 4:3 aspect ratio except the 240 line system which was progressive (actually described at the time by the technically correct term of 'sequential') and the 405 line system which started as 5:4 and later changed to 4:3. The 405 line system adopted the (at that time) revolutionary idea of interlaced scanning to overcome the flicker problem of the 240 line with its 25 Hz frame rate. The 240 line system could have doubled its frame rate but this would have meant that the transmitted signal would had doubled in bandwidth, an unacceptable option.
Color broadcasts started at similar "high" resolutions, first with the US's NTSC color system in 1953, which was compatible with the earlier B&W systems and therefore had the same 525 lines of resolution. European standards did not follow until the 1960s, when the PAL and SECAM colour systems were added to the monochrome 625 line broadcasts.
Since the formal adoption of Digital Video Broadcasting's (DVB) widescreen HDTV transmission modes in the early 2000s the 525-line NTSC (and PAL-M) systems as well as the European 625-line PAL and SECAM systems are now regarded as "standard definition" television systems. In Australia, the 625-line digital progressive system (with 576 active lines) is officially recognized as high definition.[1]
