The year HDTV started? HDTV timeline?

[Richard]

That's a wide open question!

From Wikipedia

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.

So what we define as high definition, HD, has been in a constant state of change / improvement. Recall that Edison thought he had achieved high definition with audio and his cylinder system. 100 years later came SACD and DVD-Audio fulfilling that audio perception.

1958 The Soviet Union created Тransformator capable of producing an image composed of 1,125 lines of resolution. Limited to the military.

1969 The Japanese developed consumer high-definition television called MUSE providing about four times the resolution of the US NTSC system.

1981 The Japanese MUSE system was demonstrated for the first time in the United States.

1983 The International Telecommunication Union's radio telecommunications sector (ITU-R) set up a working party (IWP11/6) with the aim of setting a single international HDTV standard.
