Odd radio exception
Random thought, semi-triggered by Col Green's place....
In the first few decades of radio, stations occupied a variety of buildings or parts of buildings.
You can see the variety easily in the station postcards
at American Radio Library.
Most had free-standing studios, usually custom built and highly architected. Others occupied suites in regular office buildings, generally on the top floors to be near their antenna. Others rented a suite in a fancy hotel, often on the mezzanine where the studio was visible to people in the lobby.
The only type of place they DIDN'T select was a storefront facing the street.
Most businesses started by renting a cheap storefront, then moved into their own building or a suite in a skyscraper after achieving success.
