I post to show that almost all sporting events that I know of are losing fans. I have no idea why they are but it is what it is. The author below seems to think he has the answers,.MLB is primarily now a regional sport, and there is high engagement at that level with the regional sports networks. While an average of 13 million viewers is not to be minimized, and was far and away the most popular thing the Fox network had to offer its viewers this fall outside of NFL football, these simply aren't the kind of numbers expected from a Boston vs. Los Angeles series.
It somewhat feels like the NFL and NBA are national sports leagues with national superstars driving interest, and MLB and NHL are regional ones. That Mulvihill MLB / NBA comparison invites a lot of interesting debate though
How this relates to NASCAR, which is a form of auto racing, is pretty pointless. Same with golf, tennis, the Olympics, you name it that isn't a franchise based league.
70 million is a 15 year low.
That’s not good for MLB either. Attendance dropped by 4 percent this season, falling below 70 million for the first time since 2003
