That was June, 2007. It was a requirement for manufactureers to begin
development, even if there was no FCC approval and few receivers


They started making and retailing radios before the start date?

"They" is a few second or third tier specialty manufacturers and one or two
others with a single offering at a high price to satisfy a need for a
monitor receiver at the converting stations.

The $200 million radio ad campaign was a year and a half before the start
date?

This was one of the requirements of the interested manufacturers.... and it
actually started about 9 months prior to FCC approval of HD. The $200
million figure is the value of airtime contributed by HD Alliance
stations... by no means all the HD stations on the air at the time.

"HD digital radio receivers are currently manufactured by more than 15
companies, including Audio Design Associates, Kenwood, Alpine, Panasonic,
Boston Acoustics, Polk, Day Sequerra, Radiosophy, Delphi, Rotel, DICE,
Sanyo, Eclipse (Fujitsu), Yamaha, JVC and Visteon."

Very limited lines, totaling less than a dozen models, some hard to get.
Many were first generation, like the dreadful BA Receptor.
