It's called the Olympic Games, not the Olympic Sports...
Bowling continues to be on the radar of the US Olympic Committee, and merging ABC, WIBC, and YABA, is in part, coming into compliance with Olympic rules for a single governing entity.
Once the USOC has all of its criteria met, then it will become an issue for the International Olympic Committee. Some say it will never happen. I believe, in time, all things are possible.
The bottom line for the IOC is profits, just the same as any buisness entity. In the past three Olympic seasons, the only time the stadiums have been filled is when the USA hosts. In every other country people were bussed in to fill the seats for the cameras
, so it doesn't look like no one goes to it. This is a reflection of the bottom line, whether it is transparent to the public or not.
With the continuing problems of judging errors, and doping scandals, the IOC will find itself hard pressed to uphold public interest and integrity. Without a strong public interest, there is no means of supporting the games.
If the public demands an Olympic game of bowling, and shows an interest in going to view it, it will provide assistance in adding the game to the roster of included games. But the wheels of the Olympi Committee turn slowly, so I don't expect any great changes soon.
