William Lear, of Learjet fame, was a distributor of Earl Muntz\u2019s \u201cStereo-pak\u201d cartridge system.<sup data-fn=\"6d4624da-3182-46b9-a055-5936ea9fdc4e\" class=\"fn\"><a href=\"#6d4624da-3182-46b9-a055-5936ea9fdc4e\" id=\"6d4624da-3182-46b9-a055-5936ea9fdc4e-link\">1<\/a><\/sup>  Muntz had revised a previous design for a three-track magnetic tape cartridge used by radio stations for commercials into a four-track cartridge for automobile stereos.<sup data-fn=\"0021ae39-34ac-4a9d-aaa8-0a6ce232aec1\" class=\"fn\"><a href=\"#0021ae39-34ac-4a9d-aaa8-0a6ce232aec1\" id=\"0021ae39-34ac-4a9d-aaa8-0a6ce232aec1-link\">2<\/a><\/sup>  Lear, who installed the same cartridge players in his jets, was frustrated by the consistent jamming of the Stereo-paks and began to redesign them. Lear was able to double the tracks on a tape in a cartridge while simplifying the design of the cartridge itself. The \u201c8-track\u201d tape was able to hold twice the recording time compared to Muntz\u2019s design &#8211; 80 minutes compared to 40 minutes &#8211; at the cost of fidelity.<sup data-fn=\"32adb50f-ce1b-430d-b9bc-90190c6af811\" class=\"fn\"><a href=\"#32adb50f-ce1b-430d-b9bc-90190c6af811\" id=\"32adb50f-ce1b-430d-b9bc-90190c6af811-link\">3<\/a><\/sup>  Regardless, Lear worked with Ford Motor Company to introduce 8-track stereo systems into Ford\u2019s vehicles for 1966. The move paid off, and by 1968, nearly 2.5 million 8-track stereos were in use across the United States. While acceptable for its portability and music capabilities, the 8-track tape lacked many of the conveniences provided by home stereo tape systems, such as fast-forward, reverse, and simple recording features.<sup data-fn=\"2d4530d4-2a75-4fb1-8fbb-efdb954aa548\" class=\"fn\"><a href=\"#2d4530d4-2a75-4fb1-8fbb-efdb954aa548\" id=\"2d4530d4-2a75-4fb1-8fbb-efdb954aa548-link\">4<\/a><\/sup>  Despite the resulting popularity of home tape systems, the 8 track tape remained the dominant form of portable music listening up until the late 1970s. The 8-track tape serves as the most prominent and similar cultural ancestor to the cassette, cementing magnetic tape technology as the foremost analog format for portable music enjoyment.<\/p>\n<\/div>\n\n\n<ol style=\"padding-right:var(--wp--preset--spacing--80);padding-left:var(--wp--preset--spacing--80)\" class=\"wp-block-footnotes has-small-font-size\"><li id=\"6d4624da-3182-46b9-a055-5936ea9fdc4e\">Andrew D.
