“…The connections between major record labels and radio have been investigated in works by Banks (), Killmeier (), and Percival (), and it has been well established that in the 1950s a system operated whereby radio playlists were dictated by major labels. Nichol characterizes this system as: “a kind of cartel, where the record companies decided who would be recorded, and recorded them, and who of those would be released, and when they were released they controlled the exposure of those records.” It was also not uncommon for major labels to buy back stock from retailers in an effort to manipulate charts, whereby artists whose records had been bought back charted higher, in turn prompting greater record sales.…”
