They used the blue dyed oil on a televised match a few months ago as an attempt to show it, but I feel that gives the bowlers an unfair advantage.
If there were a way to show the oil moving in real time to both the TV and live audience, I think you could start getting people interested in the game at a high level. Much the same way embedding little cameras in a poker table enabled the audience to see a live poker game unfold.
I'd also like to see the PBA fully embrace video streaming, and no, Xtra Frame doesn't count. I want to be able to watch follow an individual player throughout the 4 days of a typical PBA tournament. I have my favorite bowlers and I want to see their scores in realtime. I want to see how the lanes are changing and how the bowlers are adapting.
I love the sport; I've been bowling since I was very young. But, I too, would rather watch anything other than a PBA telecast.
