Z, In my case, I just never bought a window because "Fancy Nancy" or "Big Al" said I should. There were "live reads" back then, I know, and maybe, possibly, because they were live, they were funny.
(There was room to be HUMAN. Now all is recorded. No room for error.) The jock might flub up or whatever, but when you have the same ads on several stations, these people can't ALL need new windows....can they?

I am assuming the pay is lower and A) in the 60's 70's they did record hops, B) now they all buy windows I guess.....

The times, they are a changin'........
