The technology has gone from reel-to-reel tape to live streaming across the Internet, but some things haven't changed in the last 40 years of radio.
One of them is the music; if you find a format that people like, then your operation will survive.
So is the thinking as WQLN Radio celebrates 40 years of Erie area broadcasts, starting on January 7, 1973.
The non-profit was commissioned to air what commercial radio didn't; often jazz and classical music.
Classical music host Wally Faas says the best part of his job is expanding the knowledge of his listeners.
"Finding that information, providing it for listeners is one of the biggest joys about this job for me," he told us.
President Dwight Miller says the station will stay on the air as long as the programming meets what listeners want.
"Eighty three percent of funding right now comes from individuals" he said. "As long as these individuals want this kind of programming they'll continue to fund it."
The station celebrated the anniversary with an open house complete with punch and birthday cake.
