Regional Magazines - Why So Many?

I was browsing Magazine Renew to find a cool gift for a friend. I ran across a category, Regional, and was startled to find 40+ magazines devoted to different areas.

Let me count the ways:

1. San Diego Magazine.  Lots of sailors and high end houses.
2. Sacramento Magazine.  Who would live there if not on the government escalator?  Actually, it is a lovely area of the country, and I've actually read this magazine at a friends house.  I recall it as a very high end publication.
3. Palm Springs Life.  Ain't never been there, they tell me it's nice.
4. Orange Coast Magazine.  I assume this is Orange County California.
5. Las Vegas Life.  Sounds like the punchline to a joke about mobsters. Not that there are any mobsters in Las Vegas. And if there were, they certainly wouldn't be Italian American.
6. Indianapolis Monthly.  I've been to Indy.  Is there really that much to write about?  It's the only place I've ever been where Applebys is considered fine dining.
   
7. Ft. Worth Texas.  We got an airport and strip malls, any questions? Amigo.
8. Blue Ridge Country.  You not from around here, are you boy?  Hey, I got relatives in Ft. Worth.  Nice pickup truck, you paint that they Krylon or semi-gloss?
9. Baltimore Magazine.  Not as crime ridden as DC.  Move along, don't step in the blood.
   
10. Ghetto Weekly. I made that one up.
11. Red Neck Hot Rod and Insurance Quarterly.  Made that one up too.
12. Ten Year Old Laptop Software Development Journal.
13. Minivan Racing Form.
14. Using the AOL Browser in public.

Heh, the last five were fake, but funny.

I know there is a big market for these regional journals, and I admit to enjoying the one we get and resubscribe to every year.  But I had no idea there were so many.
