Thanks to oktobor for supporting the TIG
Well, Bob, you are right regarding the technical standards.. Thanks God, there is no US-HD and Europe-HD... they are all the same.
WHat I was trying to say was more regarding the economics of HD rather than the technical part. If economics weren't involved and PAL-based countries weren't taken into consideration, then there would not be any PAL-like HD formats (I mean based on the 50Hz frequencey such as 50i). I cannot see why US would care about 50i and 25p otherwise...
Also in Europe, things are a bit more complex. ATSC is not only about HD but DTV (Digital Television) in general. This involves financial agreements between countries, broadcasters, etc. In Europe this is governed by the EBU not the ATSC...
Anyway, in my opinion, the organizations that initially defined the HD standards missed a huge point: digital television will eventually prevail, and this means that the actual transport of images is radically different from hertzian. The actual decoding and presentation of images could be integrated into TV sets or HD receivers... but again I'm expecting too much.
Regarding HDTV broadcasting in the US, you are perfectly right. But again, the main advantage of the US is a huge unified market speaking the same language.... Europe has this enormous drawback of not being economically united (except the money and some trade rules) and also has a huge barrier with the different spoken languages.
Regarding the HD TV sets, Europe is doing pretty well. I live in Switzerland and in the last few years we had like 30% growth in the aquisition of HD-ready TV sets. The problem is the content. In the US again, you have huge networks like HBO which is capable of filling in the pipes with HD content. In Europe, nada (or almost).
And here is my 2 (euro)cents: As long as European countries consider film making just as an art and not an industry, they will never reach the level of the US film making business (features, TV series, etc)

They already have. Where do you think that 1920x1080/24P comes from?
The USA is the first country to massively deploy digital HDTV.
Whichever standard is broadly implemented first is likely to succeed.
The global economy has changed dramatically over the last ten years,
so we can expect considerably more re-use of technology than there
used to be.
Since as you say, ATSC HD is based on layered standards, the PAL-based
countries are free to re-use the image structure while chosing a
broadcast modulation scheme which is a better fit for the broadcast
model used in those countries.
As you say, HD is all about economics. HD has been taking off quickly
in the USA, but primarily for customers purchasing sets of 40 inches
and larger, and (until this year) more due to the popularity of DVD
than HD. Compelling content is critical, and luckily such content has
been available in the USA for over five years now.
