Well, we’re all getting older, and what’s relevant here is that the median age of the World Series viewer is creeping up and remains considerably higher than that of viewers of the other sports’ marquee events.
Jonathan Mahler of Bloomberg explains why this is a concern:
For the time being, baseball can still sell plenty of ads for luxury cars and financial services and Viagra against its demographic. But at the end of the day, the inescapable reality is that baseball fans are old and getting older. At a certain point, about when 53.4 becomes 62.9, that’s going to be a problem.
Baseball knows this. That’s why it has been reduced to creating sideshows such as the Fan Cave, “a first-of-its-kind space mixing baseball with music, popular culture, media, interactive technology and art.”
It’s incumbent upon baseball, I believe, to try to get the people who consume baseball via a laptop, a phone and a Roku player to, come playoff time, switch on the TV, because that’s where serious money is made. Perhaps having Fox, ESPN and TBS approach baseball broadcasts in a fundamentally different way would be a good start.
