mp3PRO and HE-AAC work in essentially the same way, but AAC is more efficient.

> Sounds like it was dead on arrival

How can something that is still in deployed commercial use for many years be “dead on arrival?” Moreover, AM stereo came out long after the FM band was well established.

*HD-DVD noises*

Whatever you thought that meant.

Because being niche when you were positioned to go mainstream is a failure.

It was a combination of factors:

1) poor noise rejection of AM

2) high noise on the AM band

3) changing programming on AM (aka the rise of talk radio)

It wasn't DOA because of FM. FM stereo predated it by decades.
