Some have been bought up by people who run them down, close them and get them demolished so that houses can be built. Some do the same and turn them into big houses.
Locally I have no really decent pubs, most of them cater for food these days and serve crap beer, then there is a Witherspoons which I dont like.
Only half decent one is about 1/2 a mile away, main business is eating but he does do some decent guest beers.
It's a shame when they close - for whatever reason, ever time a little history goes with them.
