Most popular divisions

[hobart_barista]

I used to think that heavyweight was the most popular division in boxing. But there seems to be a lot of talk about super middleweight and light heavyweight
How would you see the most popular divisions from 1-5?
e.g.
1. Super middleweight
2. Heavyweight
and so on.

This question can be taken from a number of angles. A great heavyweight fight, no matter who the combatants, will always catch people's attention. But the best and deepest division out there right now is welterweight.
