Favorite obsolete formats.....

"...It’s not likely that a few online reviewers were responsible for the market failure of MD..." 

Most likely your average Walmart shopper is determining what formats are commercially accepted.

"It’s not likely that a few online reviewers were responsible for the market failure of MD. It’s much more likely that the market was simply evolving beyond lossy formats, especially for recording."

It was not because of "lossy". It was because of "physical". It was just about the time when mp3 and similar ideas sprung up.

Of formats that never properly caught on, DCC (digital compact cassette). So archaic before it ever started. Decent sound, though. I could not decide between them so now I have DCC and Mini Disc.
