The 10-inch Long-Play (LP) record is a variation on the 12-inch LP and was introduced at the same time by Columbia Records in 1948.
The 10-inch LP provided around 14 minutes of playing time per side (compared to around 23 minutes on the 12-inch version) at 33⅓ rpm.
The 12-inch format was initially used for higher-priced classical recordings and Broadway shows, while popular music appeared on 10-inch records. By the mid-1950s, this changed and the 10-inch LP version lost out.
10-inch LPs would reappear as mini-albums in the late 1970s and early 1980s in the US and Australia as a marketing alternative.
