It might be hard to remember this far back, but once upon a time, some of us hoped that public TV would develop into a smart, sophisticated, civilized alternative to commercial TV - not a cheap imitation of it.

Making music on TV used to be as common as commercials. In the '60s and '70s, prime time was stuffed with variety shows headlined by such major and treasured talents as Carol Burnett, Red Skelton, the Smothers Brothers and Richard Pryor, who had a very brief comedy-variety hour on NBC that was censored literally to death.

'American Idol' is sometimes lumped with reality shows and it has that element - folks-next-door battling it out in a contest. But instead of fighting leeches, bugs, parasites and each other, as on CBS's 'Survivor' and other shows that imitate it, the 'American Idol' contestants, of course, sing.
