Rupert Murdoch conceded defeat this week in his battle with Google and the Internet, an adversary even more powerful than the British government. Murdoch, uniquely among the world’s media magnates, decided two years ago to create a “paywall” for the London Times that could not be penetrated by Google and other “parasitic” search engines. In effect, the paper was cut off completely from the public Internet. As one of Murdoch’s newspaper managers later described this strategy: “Rupert didn’t just build a paywall; he circled it with barbed wire, dug a moat around it and put crocodiles in the moat.”
