Lots of talk in the news this week about Disney buying significant parts of 21st Century Fox. It's not clear yet what exactly they may be buying, but it has pretty big implications for sports fans.
It looks like Disney could be purchasing the Fox regional sports networks. As a Detroit fan, it would be great to consolidate the Tigers, Wings and Pistons under the ESPN umbrella, where most Michigan football and basketball games are already broadcast and streamed. However, it sounds like Fox will be keeping FS1 and the regular Fox broadcast channel.
Fox owns 51% of the BTN, and that may be moving over to Disney as well. IMO if the BTN got ESPN production value it would be an upgrade.
Part of the reason the B1G conference has so much TV money is that they have been very successful in playing potential broadcasters off each other to get max value, which is why Fox started broadcasting B1G football this year. I thought an ABC/ESPN/FOX congolomorate would reduce the B1G's leverage at first, but after further reading it looks like they will stay separate for now.
Outside the sports world, lots of big movie franchises would move, and be unified, under Disney. This includes Marvel characters and all Star Wars movie rights.
The articles below have more information. The WSJ one in particular focuses on the impact to sports fans and cable subscribers/cord-cutters, and how sports TV rights are an important piece for anti-trust regulators to consider as part of the deal.
