FOR THE WEEK OF JUNE 18, 2018

DEAR JERRY: Similar to your list of chart-topping R&B records by label, it would be interesting to see a list of No. 1 Pop hits by label. My years of interest would be 1940 to 1974. And would you be able to sort them in five-year groups during that 35-year period?
—Charles Frodsham, Beloit, Kan.

DEAR CHARLES: Here they are, shown according to your specifications. The list also reflects how many more labels were making records in the 1960s and '70s.
