By '76, "Stairway" had become a hot item in most Top 40 stations' Gold libraries. The original copies of LED ZEPPELIN IV were five years old and had seen better days. Atlantic was getting a large number of requests from Top 40 stations to re-service the album.
Correct. By this time, AM Top 40 stations were competing with FM stations that played album cuts like this. One station in particular was WNBC AM, which at the time was programmed by a guy named Bob Pittman. A few years later he started MTV. Now he runs iHeart.
How far from the original topic are we now?
