A generation ago, several fledgling cable networks proffered the premise, if not the promise, of being both entertaining and enlightening.
And for awhile they were.
Shows on A&E evoked its Arts and Entertainment name, as did shows on Bravo, named after accolades for fine arts performances.
TLC proudly espoused its educational mission as The Learning Channel. Animal Planet and Discovery did the same by using programming to promote interest in the natural world, and viewers could time travel via the History Channel.
From history to current events, context could be found on CNN, which was widely derided at its inception but soon grew into a solid, even stolid source of global news.
Things are different now.
Sure, these networks still entertain. But the goal of enlightenment seems to have dimmed.
Among A&E's most notable shows is "Duck Dynasty," and Bravo has called "curtains!" on the theater and now hews to Shakespeare's "all the world's a stage" ethos with the "Real Housewives" franchise as well as other reality shows.
