Golf has, thank goodness, an established tradition of quiet commentary and respect for the game as it is played. I don't include golf as an endangered species. I have not watched many fishing competitions and cannot comment on them. Baseball, boxing, football, tennis et al, are in trouble. Yes, we need better commentators, but I believe the reason there are problems is that the broadcasters, themselves, are encouraging the gratuitous filling of dead air. I wonder if they teach all these ex jocks broadcasting techniques that include finishing whatever they're saying no matter what has just happened in front of them, including, knockouts, home runs and spectacular plays. The very idea that dead air in sports watching is a no-no, insults the intelligence of sports fans. They tune in to watch. They do not tune in to be distracted, and forced to mute the sound or change the channel. That's real dead air. Nobody buys a car if they've tuned out. But, I'm not trying to reform the industry. I just want to watch the events unburdened. Will getting a theatre sound system be of any use?
