The Central Intelligence Agency is commonly known as “The Agency.”
The movie/television industry is referred to by people in show business as “The Industry.”
What other organizations, locations, & other stuff are known as “The [whatever]” even if they’re not unique?
What I’m gunning for are things that are officially known as Such-and-Such [Thing] but are colloquially referred to as “The [Thing]” – for example, L.A.'s San Fernando Valley (one of multiple named valleys, but commonly called “The Valley”) would count, whereas The Band would not.
I thought CIA was not “The CIA” for the same reason you don’t say “THE God”. At least according to the film The Good Shepherd. Although they are inconsistent in the use of THE on their own web site.
Anyhow,
Wall Street is often called “The Street”.
Law, accounting and consulting firms frequently refer to themselves as “the firm”, which thanks to The Firm by John Grisham now sounds more sinister and pretentous than simply saying “the company”.
In most union contracts, the formally defined terms of art for the two parties are “The Company” and “The Association”, “The Organization”, or some similar generic.
I’ve heard journalists rather pretentiously refer to their newspapers as “the Paper,” whereas everyone else say “the Courier.” Not sure what’s up with that.
People in the bay area refer to San Francisco as “the City” also. When in college, anytime some one said they were going into the city, I’d comment that it was a long drive to LA.
