I find it unlikely that this trend affects 100% of the stations I listen to but none of the other ones.
No syndication on K-Bay. No syndication on KOIT. All Local on the Fox. Just last week, Cumulus replaced a syndicated morning show on one of their NYC stations with a live & local announcer. If a live & local morning show would get KFOG a 2 share, they'd post an ad right now.
Ehh, not true about the KFOG morning show. The live and local morning show was popular when Dave Morey was at the helm. After he retired, they were never able to (or didn't care to) find anyone interesting to replace him.
So you want someone who's not only local, but also "interesting?" They hired Matt Pinfield, who was respected and had incredible heritage with the music community. What was wrong with him? What's wrong with Woody? Just because his show comes from LA doesn't mean he's not the same guy who was in San Francisco. Sometimes a station has to reach outside the market to find someone interesting.
