Thanks to these policies and the poor sound quality of 78s, records took a while to catch on. In the 1920s, Thomas Edison released a competitor to the 78, the Edison disc, which was much thicker (a full quarter-inch!) and featured better audio quality. But the Edison disc required its own expensive phonograph, and it was discontinued in 1929, the same year opera star Arturo Toscanini declared that he would never record anything because a record could not fully capture the beauty of his voice.

Even so, record companies released a wide variety of genres on 78s, from classical to pop to recorded animal noises. In fact, classical releases spawned the origin of the term “album”: because each side of a 78 could only hold about five minutes of music, hour-long symphonies had to be divided into six discs, which were bound together in something resembling a photo album. Seventy-eights were better suited to short pop songs, but this length limitation would prove to be the format’s biggest weakness in the decades to come.

Still, 78s gradually gained acceptance, helped along by the popularity of jukeboxes after the Depression. Then, in 1942, the American Federation of Musicians declared that it would not record anything that did not directly help the American war effort—shellac was scarce, and it was an important material during wartime. The moratorium on record manufacturing lasted until 1944. When production got back on track, though, much of the shellac used for new records was recycled, which resulted in lower-quality discs.

Even so, shellac was on its way out anyway. In 1948, Columbia released the 10-inch LP; when Victor responded with the 45 in 1949, the “War of the Speeds” was on, and the industry soon switched from shellac to vinyl, which was much more durable and allowed for thinner grooves and, thus, longer playing times per side.

In the mid-1950s, seven-inch vinyl singles began cutting into the popularity of 78s even more. Indeed, 1958 was the last year the 78 was the best-selling format in the United States; within five years, 78s were no longer produced in any Western countries, though foreign labels like EMI’s Indian division kept producing them for a bit longer.

Since then, the 78 rpm speed and format have been revived a few times as a promotional gimmick, but these records are generally pressed on vinyl rather than shellac. One example was the Sundown Playboys’ “Saturday Nite Special” in 1971.

The most collectible 78s today are those from the late ’50s, when 78s were less common and releases were often pressed on multiple formats. In the U.K., for example, Elvis Presley’s “A Mess of Blues” is highly collectible as a 78 because it is much easier to find as a seven-inch vinyl single.
