Today in History - 1949

The Radio Corporation of America, sometimes known as RCA, announced a new 7-inch, 45 rpm phonograph record. Soon, the 45, the record with the big hole in the middle, would change the pop music business. RCA even manufactured a record player that played only 45s -- with a fat spindle that made "stacking wax" real simple and automatic for those romantic times when hands were just too busy to be flippin' records.
