The granting of rights stipulates in principle that if a school interrupts before the end of the media rights contract, the conference retains the television rights to its football and basketball matches. In this context, no school is expected to leave the conference before the end of 2025, unless it takes on a massive legal challenge. In addition, three out of four other Power Five conferences have similar provisions for granting rights, which actually limits any movement until the middle of the next decade. The SEC is the only conference not to do so because of its unwavering strength and loyalty of its member institutions. The Big 12 officially began exploring the expansion in July, a day after ACC and ESPN approved a 20-year rights extension until 2036. ESPN has agreed to collaborate with ACC on a new network that will debut in 2019. A Big 12 network is currently not under discussion, Bowlsby said. Prior to this deal, the Big Ten and Pac-12 also had similar gor deals.  The Big 12 then helped the CCA develop its GOR agreement.
 Four of the five major conferences now have such agreements, with the SEC being the only exception. As previously noted, Big 12 schools that wish to leave prematurely could challenge the granting of rights in court. However, the league has taken the extra step of integrating into Delaware, where the law makes it less likely that members could direct sovereign immunity so as not to be sued by the league. Considered a "foundation of stability" by league members, GOR has enabled the Big 12 to be "positioned in college sports with one of the best media rights deals, which offers the conference and its members unprecedented growth in sales and sports programs across two networks." All members approved the GOR and subsequently agreed to extend the original contract from six years to 13 years to match the duration of their television contracts.  Why 2023? It starts with the expiry of television contracts. Both the ACC and the SEC have long-term duty subsidy agreements until 2035-36 and 2033-34 respectively. But the other three Power 5 conferences have deals that end around the same time (the SEC`s Tier 1 deal with CBS runs through 2023-24). Last summer, the Big Ten opted for a shorter deal with Fox and ESPN, which runs through 2022-23. The Pac-12 agreement expires after the 2023-24 sports year and the Big 12 one ends the following year. Member schools have granted their sports media rights to the First and Second Leagues for the duration of their current televised agreements at the conference. ESPN and Fox could, under the current contract, be on the hook for $800 to $1 billion in Big 12 revenue if the conference adds four teams.
