Innova tried that with the USDGC and it hasn't worked out as well as they'd hoped. Hence the changes made a couple years ago. DG is harder to film than regular golf and even harder to spectate live for. Not exactly a lot of gallery space out there in Charlotte. Most people who play DG don't watch it online or in person. They'd rather play themselves. Those of us who discuss it here, on FB and even on DGCR
are a drop in the bucket in relation to the numbers of people who actually do play the game. Also, many got into DG because it's a cheap game to play. It's very hard to market to folks who aren't interested in spending money.
