Technically, Japan did offer analog HDTV service many years ago, using an 1125-line raster to deliver a 1080i image.

jsowers is apparently one of the lucky few in America that still gets open digital cable (unencrypted QAM, or, even more unlikely, ATSC).

The vast majority of CATV systems in the USA encrypt EVERYTHING on their system (with perhaps the sole exception of an analog channel 3 with a slide showing the telephone number to the company's new subscription office). This allows the CATV company to shut a customer off without actually sending a person to unplug a cable on a utility pole, meaning they can layoff several employees who did so.
