What happened is that the actual head showed up and squeezed everyone else into a tail. Previous tail has been pushed out into a long tail.
If you have had a chance to work with the companies in the content scene, you would recognize the pattern. A couple of top tier accounts (head) account for the lion's share of hot content and hence monetization, the next level of accounts (tail) - dozens to hundreds - has some hot content and hence monetization but at a fraction of the previous tier. Finally the rest of the accounts have nearly no hot content and hence no monetization (long tail).
From an outside perspective based strictly on the content itself it is very difficult to determine the difference between tail and long tail. It is even unclear the difference between some of the long-tail and the head.
