45 rpm jukebox singles

45 rpm vinyl records, the singles that dominated jukeboxes and 20th-century music culture.

About this subject

The 45 rpm record, also known as the 7-inch single, was introduced by RCA Victor in 1949 as a competitor to Columbia's LP. Featuring a larger spindle hole (1.5 inches) and a speed of 45 revolutions per minute, it quickly became the standard for popular music singles, particularly in jukeboxes. Each side typically holds one track, enabling quick changes and continuous playback in automatic machines.

Jukeboxes reached their peak in the 1950s and 1960s, relying on these records to offer a varied selection of hits. The machines used a mechanism that selected the record based on a code of notches on the edge, allowing the user to choose a song from a panel. The 45 rpm records were more durable and easier to handle than fragile 78 rpm discs, and mass production made music more affordable.

In Brazil, the format was widely used until the 1980s, with labels like Odeon and RCA releasing hits by artists such as Roberto Carlos and Raul Seixas. The singles were popular at fairs and record stores, and essential for radio stations. Today, original 45 rpm jukebox records are collectible items, with prices varying by rarity and condition. Nostalgia for the format has led to a revival among DJs and audiophiles, who appreciate analog sound and cover art.
