If everybody who whines about it would stop supporting it, we'd see a change. But, slaves loves dey bread and circuses.
I have watched one Super Bowl since 1992. Part of that is work related but mostly for the reasons you cited. I have a couple of exceptions but sports has become unnecessary in the grand scheme of things. Still, I am passionate about almost any sport from boxing to baseball....of the 1970s and 80s. :-)
