How Popular was Mitch Miller in his Heyday?

Here's his track record on Billboard's Top 200 Albums from 1958 to 1961.

14 albums in a little more than 4 years, all but 2 reaching the top ten.   Total chart time:  1,274 weeks.  By comparison, Elvis's best-charting album, G. I. Blues (debut 10/31/1960) spent 111 weeks on the Top 200, 10 weeks at #1.  (Of course, Elvis kicked Mitch's butt on the Hot 100 singles chart -- reaching #1 18 times compared to Mitch's uno.)
