The Birth Of The LP

On June 19, 1948, Columbia Records unveiled its 33 1/3 rpm "LP" record, the first long playing phonograph record to actually be successful after other record companies failed in their earlier attempts.  Prior to the LP, the most prevalent format was the 78 rpm disc, which held only 4 minutes of music per side.  That limitation is why most recordings from the swing era are less than 4 minutes.  With the LP, music fans could listen uninterrupted for up to 25 minutes each side.
