The first major example is about the availability of TV shows and movies on Netflix, but this isn't a reflection of consumption at all, or even of Netflix. Movies went down because other studios pulled their movie content. But it also shows that TV shows quadrupled from 530 to 2,108. That's big-time long tail increase.
The next example is about more sequels in theaters, but theaters have never exhibited long-tail characteristics to begin with, so that's irrelevant.
Then it goes on to Spotify and admits that it hasn't reduced its long tail, but says he "wouldn't be surprised". That's not evidence -- that's nothing. Then he claims that long-tail artists can't make a living on Spotify -- but the long tail has never been about content creators making money, that would be nonsensical in the long tail. It's always been about the platform making money from it.
Then he finally moves to a fast-food restaurant and discovers that loyal customers make up most of revenue. Which, once again, has nothing to do with "long tail" because the long tail is about products, not customers.
He finally concludes:
> We live in a Short Tail society. And it’s getting shorter all the time.
Yet provides zero evidence for this, and it's easily refutable just by looking at television. We used to all watch the same shows, now we all watch different shows. It's common to mention your favorite show and not only has your friend/coworker not scene it, they've never even heard of it. Same with your favorite band, same with your favorite author. Total available content has exploded. We live in a Long Tail society.
