Since 2010, the NCAA has had a joint contract with CBS and Turner Broadcasting. The coverage of the tournament is split between CBS, TNT, TBS, and truTV. Broadcasters from CBS, TBS, and TNT's sports coverage are shared across all four networks, with CBS' college basketball teams supplemented with Turner's NBA teams, while studio segments take place at the CBS Broadcast Center in New York City and Turner's studios in Atlanta. In the New York-based studio shows, CBS' Greg Gumbel and Clark Kellogg are joined by Ernie Johnson, Jr., Kenny Smith, and Charles Barkley of TNT's Inside the NBA while Seth Davis of CBS assists with Casey Stern and various NBA TV personalities. While two of Turner's NBA voices, Kevin Harlan and Ian Eagle, are already employed by CBS in other capacities, they also lend analysts Reggie Miller, Chris Webber, Grant Hill, and Steve Smith and secondary play-by-play man Brian Anderson to CBS. In turn, CBS announcers Jim Nantz, Brad Nessler, Spero Dedes, Andrew Catalon, and Carter Blackburn appear on Turner network broadcasts along with analysts Jim Spanarkel, Bill Raftery, and Dan Bonner. The current contract runs through 2024 and, for the first time in history, provides for the nationwide broadcast each year of all games of the tournament. All First Four games air on truTV. A featured first- or second-round game in each time "window" is broadcast on CBS, while all other games are shown either on TBS, TNT or truTV. The regional semifinals, better known as the Sweet Sixteen, are split between CBS and TBS. CBS had the exclusive rights to the regional finals, also known as the Elite Eight, through 2014. That exclusivity extended to the entire Final Four as well, but after the 2013 tournament Turner Sports elected to exercise a contractual option for 2014 and 2015 giving TBS broadcast rights to the national semifinal matchups. CBS kept its national championship game rights. Since 2015, CBS and TBS split coverage of the Elite Eight. Since 2016, CBS and TBS alternate coverage of the Final Four and national championship game, with TBS getting the final two rounds in even-numbered years, and CBS getting the games in odd-numbered years. March Madness On Demand would remain unchanged, although Turner was allowed to develop their own service.
