【简答题】
Text 2 Here' s how I want to watch the 2014 Winter Olympics . I want to go to a Web site to see any event I want, whenever I want to watch it, on whatever screen I choose . I' 11 gladly pay . The technology exists to make this happen today . Yet nearly two decades after the introduction of the World Wide Web, this remains a fantasy . NBC, which broadcasted the Vancouver Olympics in the United States, wouldn' t put videos on its Web site until they had been shown on prime-time TV . So Americans had the weird experience of learning from a news report during the day that something fantastic had just happened, and then having to wait until that night' s broadcast to see it . Bloggers complained, but NBC wouldn' t give way . Its research shows that people like me, who want to watch the Olympics online, represent only 7 percent of the total audience . The other, bigger concern is: the Internet doesn' t deliver any money . Advertisers remain willing to pay big money to show their commercials on prime-time TV . But on the Internet? Not so much . So NBC clings to the old way of doing things . As it sees it, the prime-time show is the most important . To make matters worse, NBC was already expecting to lose $ 250 million on the 2010 Vancouver Games . Good luck persuading it to invest in a risky Web project . It's easy to blame the network executives . But the NBC guys and their like are only doing what makes sense . They're going where the money is . That needs to change . Yes, selling reporting of Olympic events over the Internet would drain away some of the prime-time audience, but my sense is many of the online subscribers would still watch the prime-time show . And over time, the subscription dollars could become a substantial rev- enue stream. Instead of viewing the Internet as a threat to prime time, the TV networks should see the Web as a way to sell even more of their product to a small but passionate subset of their audi-ence . I' m hoping that by 2014, that will have changed .
