Pittsburgh-based Sheridan Broadcasting Corporation, which operates news and gospel network programming in more than three dozen markets nationwide, has filed for Chapter 11 bankruptcy.

Once owner of radio touchstone WAMO, Sheridan still is majority owner in the American Urban Radio Networks. Sheridan, a privately owned company, was founded in 1972 by the Davenport family.

Seeking Chapter 11 protection, common in business, allows time for a company to reorganize.
