In the ideal, I'd be interested in the PGA played in a more international, "World PGA" basis, but I think the limit that can go practically is to the North/South Am "western" hemisphere... economy is not going to give up the US "timezone" TV audience...unless of course the increase in world subsidiary rights well compensates for the lowered US ad rates that come with early morning/night finishes for a sport that already ranks lower. It wouldn't destroy or hit those rates very much, because golf already has advertising partners, it just wouldn't increase them.
As to venues, just on my own interest/renewal.
PGA:
Greenbrier? I don't know the long term fate of the tournament they've had there but I like watching golf on it...something in Ohio? It seems that there are far too many interesting courses to not host something there again, without destroying it to do so. What about a Caribbean course or something like Mid Ocean?...I mean screw it, on site, these events are a rich person's corporate entertainment mall anyway, so what do you care you can't afford to bop out to Bermuda for a 5 day jitney...
US:
I was watching highlights of both the 95 Am and the 2006 USWO, and realized that we lost the USSrO at Newport last year. I don't know how that place handles a big tournament, but I'd like to see elite men's play on it again. It's kind of a shame that two of the highest rank world courses for a century, Pine Valley and Cypress Point rarely are seen. If the TV eye candy of Sawgrass, PB, Augusta, draws the causal fan to golf, imagine what they'd see when the modern HD drone coverage hit those fabled courses....us too.
Open:
Outside of the impossibility of going to Prestwick, I have to rely on the UK contingent to guide to me as to what I'm missing, and what would make for a lively competition. As it is, I like watching golf on the current rota and I would like to keep seeing those courses at least in the 5-7 year windows they currently follow. I pine for more opportunities to see them...***
***Now that the Am. PGA is placed (sensibly, imo) in May, I wish world golf would give way to a GBI heavy segment, starting with the Open, whereby the cream of all golf would play both the off year rota courses and some of the other suggestions we've heard or could hear on this thread. The fans could really do without that faux FedEx thing...let elite play be congealed in GBI/Europe from July 10 - Sept 1 and then reconvene for the Am Tour championship in favorable climes for the subsequent month.***
