Unlike NBC, which airs reruns of the most anticipated Olympic events of the day, NBCSN airs Olympic events live. The network also extensively covers the National Hockey League and the Premier League in England, also carrying limited college football, basketball and hockey. NBCSN also airs news & analysis programming; since parent company Comcast purchased British broadcaster Sky plc in 2019, NBCSN has simulcast Sky Sports News during the early afternoon hours. Unlike ESPN and Fox, the network does not have a flagship, all-sport newscast, with its news and discussion programs generally centered around individual sports. The network's attempts at general-purpose shows have typically been short-lived. During NBC and NBCSN's coverage of the Olympic Games, sister network Olympic Channel (and before that, its predecessor Universal Sports) flips to an all-sports news format, providing summary coverage of the day's Olympic events. CBS Sports Network was founded as "College Sports TV". It still maintains a primary focus on college sports, but has since broadened to include general studio discussion shows, simulcasts of CBS Sports Radio talk shows, and some lower-end professional sports. On February 26, 2018, CBS Sports launched CBS Sports HQ, an Internet-only channel that serves as a 24-hour channel for sports news, highlights and discussion programs, without any live sports. ESPNU is a 24-hour sports news network dedicated to college sports. ESPN airs a customized version of SportsCenter, SportsCenter U, covering college sports, as well as documentaries about college teams and players. The Big Ten Network, whose origins can be traced back to '03, airs a large amount of original sports programming, including a program similar to SportsCenter called Big Ten Tonight, as well as live sports. Unlike other college sports channels, such as ESPNU or BTN's sister station Fox College Sports, BTN covers the Big Ten Conference exclusively. Fox College Sports (FCS) airs an extremely large amount of live sports. Because Fox Sports has so many rights to so many college sporting events, FCS networks are split by region, similar to Fox Sports. Launched in 2011 as a joint venture between ESPN & the Texas Longhorns, the Longhorn Network airs over 20 different live sports, as well as sports news & analysis. Three years after the launch of the Longhorn Network, ESPN entered a similard joint venture with the Southeastern Conference, also known as the SEC. While it does broadcast over 20 different SEC sports, it also airs analysis of upcoming games as well as a sports talk show.
