From what I gather, Motown was still a small operation headed up by a single entrepreneur, Barry Gordy using the converted house ("Hitsville") on West Grand to make that musical magic. No, by 1970, Motown was one of the leading state-of-the-art recording companies in the country. Their domination of the Top 40 charts was nearly unrivaled. The old house on West Grand was pretty much an historic relic by that time.
This may be the "thread that never endeth". Thanks to your various followups, Windflier, and some additonal digging, I just now found out that one of my favorite television miniseries, "Lonesome Dove" was produced by
Motown Productions. It's an understatement that Berry Gordy, below, launched quite an influential company.
