Who is the most famous boxer in the world right now?

They are pretty unknown to the wider public though.  I bet if they walked down the street anywhere in the world outside their home countries, they'd barely get recognised.

I think boxing is almost back to where it was in the 90s in Britain.  There have definitely been far more world champions here recently than probably any other time in history, but the TV viewing ratings aren't quite there yet, but that's because it is harder now to get mass audiences because there are more channels and the internet, plus there used to be a lot more fights on free television here in the 90s, big fights too.  In that sense it is probably impossible to emulate the 90s in the modern day, but arena and stadium turnouts are probably eclipsing it though.  Certainly by revenue and probably by numbers too,

The huge draws in 90s  Britain were Frank Bruno, Lennox Lewis, Nigel Benn, Chris Eubank and Prince Naseem.  (The Benn and Eubank rivalry was huge here, but probably not as big anywhere else).  All 5 of them attracted huge TV audiences whoever they were fighting (although maybe not Lennox Lewis, but that's because he never fought on free television when he became known to the public, but his fights were certainly as big on subscription TV).

I think it is pretty comparable in the last 10 years.  The huge draws of the past 10 years would be Ricky Hatton, Tyson Fury, Anthony Joshua now, David Haye, but then there are a bunch of fighters on the rung just below but not quite there, like Amir Khan, Kell Brook, Jame DeGale, Joe Calzaghe, Carl Froch, Chris Eubank Jnr, Tony Bellew, Billy Joe Saunders, which I don't think the 90s had an equivalent of, so actually the strength in depth is probably stronger now overall, if maybe the biggest names aren't quite as big as they were.

Yeah, Naz cited the hand injury as the reason for retiring.  There is also an interesting interview he did with Sky on the Barrera fight (I think it is on youtube), he says he took the fight really late and he had to do it because he was contracted by an American cable network to take it (I think HBO), so he had to lose an enormous amount of weight at the last minute, and the day before the fight he couldn't even stand up he was so exhausted.

It might not be a popular view, but I think he was the most talented fighter this country has ever produced.  I remember my next door neighbours mum, before he was even that big, used to always tell me "he's too arrogant", but my response was always "but he's gonna be a winner, haven't we had enough of losers like Frank Bruno yet?".  I suppose as long as everyone has an opinion on you one way or the other, you're gonna make money in boxing.  My opinion of him as a person though is pretty low compared to my opinion of him as a boxer.

Sad about Ricky Hatton, he was always putting on a lot of weight between fights so it was bound to catch up with him eventually, he's been in the tabloids because of his drug problems, I don't think I've seen the video, certainly read about some of his exploits.  I guess it is hard to replace boxing for some when you quit, I think he is doing some small promotions and coaching now, so hopefully he is getting his life together.
