Where's all the HD content?

It would seem that our reluctance is coming back to bite us in the arse.  Engineer Live is reporting that even though the Govt has addressed the issue of regulating HD and the hardware is available to consumers, we are still missing out on wide spread HD adoption. DTV services are not transmitting HD to its customers. At least not enough to inspire new customers into the market. Why buy that new TV, when there are no shows which are going to benefit from it. They go on to say:

“However, a majority of consumers in the United States receive digital content through subscription services from satellite or cable providers. Although this programming arrives via a digital cable or digital satellite signal, it doesn't mean it is in HD format, that is a minimum resolution of 720 lines with progressive scan, or 1080 lines with interlaced scan… Concerns among content providers are limiting the amount of HD programming that is being broadcasted, inhibiting greater consumer purchasing of DTV sets.”

This problem extends from the broadcasters and cable companies in another direction as well. Producers are just not making the programmes.  Truth be told this baffles me. When I left a medium sized broadcast post house three years ago to join Pogo ( a much more nimble outfit). I think my perspective got clouded because we focused on HD almost exclusively. After a break in work in the new year, I returned this summer with the assumption that every TV programme would now be produced in DH with the exception of low budget day time programmes that were topical and therefore dated quickly.

I have since discovered that I was very wrong. I wonder where is all the hard work that has gone into establishing cost effective workflows which minimize post budget increases to under 20% in most cases.  In some cases HD can even be made cheaper than SD.  What is the delay I ask?
