The "Mirror"'s mass working-class readership had made it the United Kingdom's best-selling daily tabloid newspaper. In 1960, it bought the "Daily Herald" (the popular daily of the labour movement) when it bought Odhams, in one of a series of takeovers which created the International Publishing Corporation (IPC). The "Mirror" management did not want the "Herald" competing with the "Mirror" for readers, and in 1964, relaunched it as a mid-market paper, now named the "Sun". When it failed to win readers, the "Sun" was sold to Rupert Murdoch — who immediately relaunched it as a more populist and sensationalist tabloid as a direct competitor to the "Mirror". In 1978, "The Sun" overtook the "Mirror" in circulation, and in 1984 the "Mirror" was sold to Robert Maxwell.
