Some cinemas do present some sporting events. The rights negotiations for sporting events are multi-layered and complex. Your average soccer or MLB game is not likely to be negotiated for that venue, and a whole-season license is unlikely. Playoffs, championships, and the like are sometimes worthwhile but it's not going to be the corner mom & pop cinemas paying for that content. It's going to be IMAX or Regal Cinemas or someone huge. For example the 2024 Summer Olympics, with NBC owning exclusive rights to the US market for video coverage (meaning NBC Universal, meaning Comcast) IMAX licensed the opening ceremony to be picked up from NBC and delivered to their US cinemas over IP with fixed latency. It was only the opening ceremony and no scored events. That involved NBC, IMAX, and LTN to carry the video in between. IMAX and NBC negotiated the rights and LTN got statements of agreement on that from NBC. There was involved planning and engineering work to make sure the technical part went smoothly. I'm sure the negotiations, contract writing, redlines, and final sign-off between the source and destination took longer than the tech work.
