If you’re into music as most people are, Sony had about 25% of the world market a while back, and I believe they are closer to 30% now, and the top spot.
It doesn’t take much research to see that Sony Corp is the #1 in just about any field of electronics and entertainment.
This is one of the reasons why the other players are always beating on them.
Personally I can’t really blame them, if I was CaNikon last thing I would want is a Gorilla in the room.
