April 10 (Reuters) - U.S. broadcast station owner Nexstar Media Group NXST.O has started an effort to limit the reach of national networks such as ABC, NBC and CBS through its affiliate stations, Bloomberg News reported on Friday, citing a regulatory document and sources.
The media company has begun preventing its stations from filling local newscasts with segments produced by national networks and is asking them to use content from its NewsNation cable channel instead, the report added.
Reuters could not immediately verify the report.
