Changing the channel: How four cable networks reinvented themselves

If at first you don't succeed, change everything. Here's how typical programming has changed on some of our most popular networks.

1985: "Jazz Counterpoint." Billy Taylor chats with fellow pianists about their craft.

Today: "The Real Housewives of Atlanta." Rich women take turns backstabbing and berating each other.

1991: "Breakfast With the Arts." A tribute to the finest in music, theater, dance and other art forms.

Today: "Duck Dynasty." A Louisiana family markets its duck calls and conservative views.

1988: "World Monitor." A nightly news show produced by the Christian Science Monitor.

Today: "Deadliest Catch." A look at the rocky life of fishermen in the Bering Sea.

1987: "Captain's Log With Mark Gray." A low-key, boating-safety series.

Today: "Here Comes Honey Boo Boo." A high-energy reality series revolving around a child beauty-pageant contestant in Georgia.
