Again, just taking the tour makes you realize the influence.
Pictures of the studio in use (and the little control room) with more stars than you can imagine, and they were coming in regularly.

I'm pretty sure they had the process covered right down to actually cutting the vinyl .. so they knew exactly how to get the end result. I know they created new Labels at will. That way I Heard It Through the Grapevine could be played twice as often according to the common Radio Playlist rules at the time. If it was two versions on two different labels it could be played twice. Smokey Robinson, Gladys Knight, and Marvin Gaye all recorded that song within a couple year span.

Marvin Gaye, hired as studio drummer in the beginning, then moved up the ladder.
Diana Ross and the Supremes, Jackson 5, Martha & Vandellas etc etc.

In their day Motown was 'the sound'. And it lasted for quite a span. Abbey Road Studios may have had such a span, but not many others. Funny how close in time the success of these two studios are.

For Comparison Abbey Road has claims to recording the Beatles, Pink Floyd, the Hollies, Badfinger .. again pretty powerful in it's day.

I do not work here, but the benefits are still awesome
