WKCR is a radio station. WKCR's signal is on 89.9 FM, and it is also streamed online.
It's run by Columbia students.
Their call letters stand for King's Crown Radio. It is notable compared to other college stations in that it is not free-form and that the content broadcasted would not be heard on a regular for-profit radio station or even a regular college station. That means no ads and no indie rock or hip-hop. Instead, WKCR maintains close ties to the avant-garde and jazz communities of New York. It has a strong following outside of the immediate Columbia community, especially among New York alumni.
