Margaret Thatcher was born on October 13, 1925. A century has just passed since her birth. The Iron Lady (a nickname given to her by the Soviets when she was still in opposition) was a pioneer in many ways. She was the first woman in Downing Street and the first proponent of neoliberalism in an industrialized country, for example. But not only that: she was aware of the usefulness of what later became known as the "Overton Window," a concept that hadn't even occurred to the American Joseph Overton, still a teenager. Today, the "Overton Window" refers to the range of ideas acceptable to the public. If one wants to undertake a conservative revolution, as in Thatcher's case, it's necessary to shift the window to the right and make political measures, previously unthinkable, mainstream, or at least open to debate. For Joseph Overton (1960-2003), this task fell to ideological think tanks. Even before coming to power in the United Kingdom, Thatcher understood that the real power lay with the mainstream media. And she didn't have them. The BBC, the public broadcaster, was not in favor of neoliberalism. Neither was the traditional conservative press, such as "The Times" or "The Daily Telegraph," aligned with classic right-wing politics. The popular press, with the "Daily Mirror" at the forefront, defended Labour positions, with one exception: "The Sun," a left-wing tabloid acquired in 1969 by the Australian Rupert Murdoch, underwent a complete about-face in 1975 and became the main supporter of Thatcher's ideas, precisely in 1975 when she was elected leader of the Conservative Party. But Thatcher and Murdoch wanted more. They both wanted "The Times" and "The Sunday Times," the most influential newspapers of the time. They were owned by a Canadian group, Thompson Corporation, which in 1978 had ordered a lockout to subdue the unions, opposed to the technological restructuring proposed by the owners. Both newspapers were off the streets for a year. Thompson Corporation lost 30 million pounds in the struggle and, after this financial drain, decided to divest itself of the two "Times."
