Partnership with The Spy
In 2012, Ferris O'Brien of The Spy and Rachel Hubbard of KOSU met to discuss the possibility of The Spy producing a single show that would air on KOSU and focus on local music. Following a great deal of research and looking at the obvious void of Oklahoma music on the airwaves, KOSU and The Spy entered into an unprecedented partnership to bring a suite of shows to air.
These shows and the Spy stream maintain a heavy focus on raising the bar for Oklahoma music. The Spy retains its independence in production and as a non-profit. However, to maximize resources, KOSU and The Spy work together to bring that programming to air and to fundraise to support the programming.
The Spy airs nightly on KOSU from 7 p.m. to 5 a.m.
