People pay to see physiques and they leave all those distracting signs behind the stage. Amateurs.
sponsors want the exposure but I agree it is distracting.
Personally, I think things looked a lot better when the stage was pretty much bare and the guys posed on a raised podium. I have a video of the 1982 olympia and it is like this.... draws your eyes to the guys physique more and makes them look more impressive because of the contrast.
the way it is now there are too many things your eyes are drawn to...
