I tend to think about it this way, and for the example, let's take it back to the late 80s to early 90s.
Retirement from the PBA essentially means retirement from the main national tour. For that timeframe, that meant no longer appearing on ABC when/if you made the show, and no longer were getting the main spotlight during the biggest time bowling is televised. If you had to rank the shows in terms of available to watch (again, going back to them, and notwithstanding that all of the shows are important as far bowling goes, but let's roll with it), I'd have them as:
- PBA Tour. This was always on network/free TV on ABC, until it went off the air.
- PBA Tour. After it left ABC, it went to ESPN.
- PBA Senior Tour. Always on ESPN or ESPN2.
- LPBT Tour. Always on ESPN or Prime Sports Network, though harder to catch.
- PWBA Tour. This went to ESPN2 most of the time until it folded in 2003.
Until it went off the air on ABC, the main tour was where they always were. When the main tour wasn't on, I always caught the Senior Tour to see Earl, Roth, Dick, Handegard, Holman, Stus, Teata Semiz, and others. But at least they still had that TV time.
Nowadays they won't really have that spotlight because the PBA50 and PBA60 stops are streamed and not aired, so we'll only see them through FloBowling or if they make the TOC show. So they'll be gone from the main spotlight, but we'll still have some way to catch them.
