The Obituary
The Stereo 8 cartridge, developed by William P. Lear and introduced in 1964 before Ford pushed it into 1966 Mustang, Thunderbird, and Lincoln models, made recorded music a feature of the American automobile. Its endless loop of tape ran through four stereo “programs,” and the player’s mechanical clunk as it switched programs often interrupted a song. The compact cassette was smaller, rewindable, and recordable, and as cassette players improved through the 1970s the 8-track lost ground fast. Record labels stopped issuing them by the early 1980s, and U.S. retail sales ended around 1988.
Worth remembering
A loud 'ka-chunk' announced the player switching tracks, sometimes splitting a song in half.
Backed by Ford and RCA, it became the dominant car audio format of the early 1970s.
