Wurlitzer's original jukeboxes played only 10 78-rpm records, one side only, later expanded to 24. With the advent of smaller 45 rpm records, Wurlitzer was beat to the punch by Seeburg mechanisms which could play both sides of 50 different records, yielding 100 song choices. Although Wurlitzer ceded the crown of industry leader to rival Seeburg in the 1950s, Fuller's designs are so emblematic of jukeboxes in general that 1940s era Wurlitzers are often used to invoke the Rock n' Roll period in films and television. Wurlitzer struggled on for 20 years or so and made one final effort to keep its jukebox business viable with a nostalgic 1971 model called the "1050." The model didn't sell well and only 1600 units were produced. The jukebox line was sold to a German company in 1973.
