单选题 Old stereotypes die hard. Picture a video-game player and you will likely imagine a teenage boy, by himself, compulsively hammering away at a game involving rayguns and aliens that splatter when blasted. Today a gamer is as likely to be a middle-aged commuter playing 'Angry Birds' on her smartphone. In America, the biggest market, the average game-player is 37 years old. Two-fifths are female. Even teenagers with imaginary rayguns are more likely to be playing 'Halo' with their friends than playing alone Over the past ten years the video-game industry has grown from a small niche business to a huge, mainstream one. With global sales of $56 billion in 2010, it is more than twice the size of the recorded-music industry. Despite the downturn, it is growing by almost 9% a year. Is this success due to luck or skill? The answer matters, because the rest of the entertainment industry has tended to treat gaming as being a lucky beneficiary of broader technological changes. Video gaming, unlike music, film or television, had the luck to be born digital: it never faced the struggle to convert from analogue. In fact, there is plenty for old media to learn. Video games have certainly been swept along by two forces: demography and technology. The first gaming generation—the children of the 1970s and early 1980s—is now over 30. Many still love gaming, and can afford to spend far more on it now. As gaming establishes itself as a pastime for adults, the social stigma and the worries about moral corruption that have historically greeted all new media, from novels to pop music, have dissipated. Meanwhile rapid improvements in computing power have allowed game designers to offer experiences that are now often more cinematic than the cinema. The industry has excelled in two particular areas: pricing and piracy. In an era when people are disinclined to pay for content on the web, games publishers were quick to develop 'freemium' models, where you rely on non-paying customers to build an audience and then extract cash only from a fanatical few. In China, where piracy is rampant, many games can be played online for nothing. Finns instead make money by selling in-game perks and 'virtual goods' to dedicated players. China is now the second-biggest gaming market, but does not even rank in the top 20 markets for the music business. As gaming comes to be seen as just another medium, its tech-savvy approach could provide a welcome shot in the arm for existing media groups. Time Warner and Disney have bought games firms; big-budget games, meanwhile, now have Hollywood-style launches.
