Not trying to be a pessimist, but 15 years ago in my area bowling was very popular, to an extent still is but some of the trends are very disturbing to me:
The formation of USBC - thought at the time it would be a good idea to merge ABC/WIBC. After 10 years of this since 2005, I do not see the benefit of merging the two bodies. All I see is increase in fees and for what?
The PBA, a sport 10 years ago was my favorite to watch on tv and attend in person is surviving on a thread. I used to record every show but now...who cares? It's not a real tour anymore, nothing is live except for a couple major events and most of the events are in one city then eventually may have it an another city. Kind of hard to take seriously when the events are not live and not having a tour for everyone to see.
Bowling alleys. What year in your area was the last time a bowling alley was built? Entertainment centers like Main Event or Lucky Strike do not count. These places don't usually have leagues. They cater everything from kids to upper class drinking adults. I counted all the bowling alleys in my area and I came up with 1988 was the last time a bowling alley was built, also every time a bowling alley has been closed down nothing has took it's place.
Also, Brunswick selling their company to Bolmore was probably the nail in the coffin. Brunswick was the best thing to happen to bowling in the 1980's putting alleys everywhere, AMF has always sucked then Bolmore did nothing to improve them not they practically have a monopoly on it. Let's not talk about what Bolmore did to my Brunswick bowling alley's bar.
