For the next eleven years, the only area of the state with a clear signal from a National Educational Television or PBS station was New Orleans, which was served by WYES-TV.

Finally, in 1971, the recently created Louisiana Educational Television Authority approved the money to build and sign on the stations.

Five more stations launched throughout the state, extending LPB's signal to portions of Arkansas, Mississippi and Texas: KLTM-TV in Monroe signed on in September 1976, followed by KLTS-TV in Shreveport in August 1978, KLPB-TV in Lafayette, KLTL-TV in Lake Charles in May 1981 and finally, KLPA-TV in Alexandria in July 1983.

In 1985, Shreveport native and longtime Baton Rouge resident Beth Courtney was named president and CEO of Louisiana Public Broadcasting, a capacity she remains in to this day.

For nineteen years, political consultant, raconteur, and author Gus Weill hosted the acclaimed Louisiana Legends program on the state network.
