NBCSN is an American digital cable and satellite television channel that is owned by the NBC Sports Group division of NBCUniversal. It originally launched on July 1, 1995, as the Outdoor Life Network (OLN), which was dedicated to programming primarily involving fishing, hunting, outdoor adventure programs, and outdoor sports. By the turn of the 21st century, OLN became better known for its extensive coverage of the Tour de France, but eventually began covering more "mainstream" sporting events – resulting in its relaunch as Versus in September 2006.
Comcast, the original owner of Versus, acquired a majority stake in NBC Universal in 2011. As a result, Comcast merged the operations of its cable channels with those of NBC. In particular, it aligned the operation of its sports channels with NBC's sports division, NBC Sports. On January 2, 2012, Versus was rebranded as the NBC Sports Network (with the on-air branding later shortened to NBCSN) to reflect these changes. As of September 15, 2014, the entirety of NBC Sports' operations, including NBCSN, is based out of facilities in Stamford, Connecticut.
As of February 2015, NBCSN is available to approximately 81,578,000 pay television households (70.1% of households with television) in the United States.
