unfortunately for victor, it was downhill from there. many of the subsequent issues were not new recordings but simply dubs made from existing 78 rpm record sets. the dubs were audibly inferior to the original 78s. two-speed turntables with the  rpm speed were included only on expensive high-end machines, which sold in small numbers, and people were not buying many records of any kind at the time. record sales in the us had dropped from a high of 105.6 million records sold in 1921 to 5.5 million in 1933 because of competition from radio and the effects of the great depression. few if any new program transcriptions were recorded after 1933, and two-speed turntables soon disappeared from consumer products. except for a few recordings of background music for funeral parlors, the last of the issued titles had been purged from the company's record catalog by the end of the decade. the failure of the new product left rca victor with a low opinion of the prospects for any sort of long-playing record, influencing product development decisions during the coming decade.
