The Rev. Billy Graham was president of then-Northwestern College in 1949 when it launched KTIS radio station inside a tiny studio, with an opening prayer by Graham and a serene organ rendition of the hymn "Blessed Quietness."
The modest venture into Christian broadcasting this year marked its 70th anniversary, today reaching at least 400,000 listeners a week through 23 radio stations in 10 states from Kansas to Connecticut, the station reports. That includes two stations in Illinois acquired last month.
The traditional organ recitals and church melodies have morphed into contemporary Christian music on KTIS FM 98.5. Its sister station, KTIS AM 900, has a "talk and teaching format" and is the flagship for the Faith Radio Network.
"KTIS is one of the top noncommercial Christian radio stations in the country in terms of audience and reach," said Jason Sharp, senior vice president of the Northwestern Media network, of the University of Northwestern-St. Paul.
A rich history and consistent ownership gives KTIS and Faith Radio an unusual niche in the Christian broadcasting world, he said.
Thousands of people drive by the KTIS call letters on Snelling Avenue in Roseville every day, but most are unaware of its roots. The first studios were located near Loring Park in Minneapolis, then home of Northwestern, and it was often college employees behind the microphone.
Secretaries sang solos and formed trios, a stenographer played the organ and live programming was broadcast from Graham's office, according to station histories.
Today KTIS is housed in a modern building on the Northwestern campus in Roseville. On a recent afternoon, KTIS host Andy Youso played music and fielded audience calls in the FM studio, while in the Faith Radio studio, a few feet away, host Bill Arnold interviewed on-air guests for a segment called "Guy Talk."
