are shown on TBS (12 games), TNT (12 games) or truTV (nine games). Sweet 16 (regional semifinal) and Elite 8 (regional finals) games are split among CBS and TBS. In 2014 and 2015, Turner channels had exclusive rights to the Final Four (with standard coverage airing on TBS), and CBS broadcast the championship game. Since 2016, rights to the Final Four and championship game alternate between Turner and CBS; the 2016 tournament marked the first time that the national championship game was not broadcast on over-the-air television. The same number of "windows" are provided to CBS as before, although unlike with the previous schedule where all games in a window started within 10 minutes of each other, resulting in the possibility of multiple close games ending at once, the start times of games are staggered, with action lasting later in the night and fewer simultaneous games than in the previous format. As a result of the new deal, Mega March Madness, a pay-per-view out-of-market sports package covering games in the tournament exclusive to DirecTV, including a first and second round 'quad-box' channel showing all four games on one screen, was discontinued. March Madness On Demand (now called March Madness Live) remained unchanged, with Turner Interactive taking over management of both that service and NCAA.com at the start of 2011. The contract was expected to be signed after a review by the NCAA Board of Directors. In 2012, the service was changed; only games televised by CBS are available for free. All other games are available to authenticated subscribers to the channels on participating television providers. The 2018 tournament, with TBS televising the national semifinals and final, is the first in which those particular games are subject to authentication restrictions. In 2018, March Madness Live added a new "whiparound" stream during the early rounds known as Fast Break (similar in concept to NFL RedZone and ESPN Buzzer Beater), which features live look-ins, analysis, and highlights of simultaneous games. The CBS-WarnerMedia coverage formally begins with The Selection Show—in which the teams participating in the tournament are announced, which follows CBS's coverage of the final game on Selection Sunday. During the tournament itself, truTV broadcasts pre-game coverage, Infiniti NCAA Tip-Off, while TBS and TruTV also air the post-game show Inside March Madness. CBS also produces coverage of the Reese's College All-Star Game (held on the afternoon of the Final Four at its venue),
