TV, perhaps, but in Lowell, Massachusetts there was once headquartered a chain of discount stores known as Giant Stores(primarily in and around New England). On the 2nd floor of a huge rambling warehouse was a radio station broadcasting facility, WLLH(LL for Lowell-Lawrence). In that facility is where Ed McMahon got his radio start.
One of my radio-television-theater school classmates, while we were in school, was working there on a part-time basis. Those of you from that area of Massachusetts, or for many years in New Bedford area, may have heard Jack Peterson("Wacky Jacky") doing news and sports broadcasting. His birth name was Joel Polonsky, but only a few of us knew him as Joel. But Wacky Jacky turned the same "pots" at LLH as Ed McMahon had done, previously.
