The End Of The Loop

CHICAGO (CBS) -- It's the first day of a new era as Chicago's classic rock station 97.9 has changed formats.

WLUP hit the airwaves in 1977 and became a mainstay in local radio.

It was sold to Education Media Foundation earlier this week.

It is now a contemporary Christian music station.

You can still listen to classic rock from the Loop online at wlup.com.
