TheCash BoxTop 100 Pop Singles (also known as theCash BoxTop 100) was arecord chart in the United States for songs, published weekly byCash Box magazine, which began publication in 1942.[1] As a close competitor toBillboard magazine, it was first issued for the September 13, 1958 issue when they expanded their top 75 chart to one hundred positions. The original version of the magazine lasted through November 16, 1996.[2] WhileBillboard ranked singles weekly mixing the total airplay on radio stations and singles sales from all across North America,Cash Box presented their rankings via all sales and airplay of songs without splitting up genres in order to formulate the generalized popularity of a single's overall presence.[3] Many singles hit number one inCash Box that didn't onBillboard and vice versa.[4]
