In saying "more" tv coverage, what specifically are you thinking that they could do better at? After all, they basically pioneered the concept we enjoy today of all four rounds of a major championship being aired lived on cable television. The cable network 'USA' started covering the first two rounds live back in '82.
Or are you referencing how they never covered any of the front-nine play, adhering to the belief that "more was less" and in changing that - they would also remove some of the mystique of the tournament? Besides, the phrase that still exists to this very day, something about "the tournament doesn't really start until the back-nine on Sunday" is still very much applicable, not just at the Masters, but every big tournament that has been played since. Yet that too would change back in 2002, thanks to chairman Hootie Johnson, who decided that by starting the weekend coverage a couple of hours earlier - it wouldn't impact either the mystique or the tv ratings. So now the viewers got to see the entire golf course.
Or are you referencing the 4 minutes of commercials per hour, which continues to be by far the fewest amount of television ads per any live-televised pro golf event? (I will give Martha Burk partial credit for that one, and still thank her to this day.) They began their 56 minutes of uninterrupted televised coverage back in 2004.
Then you have their website (which you admit you're not interested in, but is nevertheless there for millions of other people who are). They started with live-streaming accessed through their website of the Amen Corner holes, 22 hours of coverage over the four days for those who want to access coverage from the internet. The next year they also included coverage of the 15th and 16th holes for live-streaming. ('07 and '08). Away from home, stuck at the office, no cable tv subscription - they had you covered.
Then came high-def television, the first major to utilize the picture quality. But they went even further. Back in 2016 they started using 4k Ultra High-Def cameras for those lucky enough to have that technology in their tv sets.
Then came the smartphone apps that they designed exclusively for smartphones, free of charge, to watch live streaming coverage via smartphone technology. Or their Masters app for Apple TV users.
I get the gist that you're not fond of the interviews, the recaps, etc. But then I think back to just about every US Open I've had to watch over the years, when tuning in Sunday afternoon you knew that you're going to have to either sit-through or fast-forward through a 30-minute dialogue opening that is more like a mini-documentary of their major championship history than it is an update on what has happened in the tournament the first three rounds. And then you get to watch 3 players putt, 2 full swings, then a MasterCard commercial. Wash, rinse, repeat, basically for the entire four rounds.
Yeah, I get that it's got a cheesy, melodramatic twist to it. But damn... for what you get in return as someone who loves the game and loves watching major championships - I can't possibly begin to ponder what more they could offer, at least compared to all the rest.
