Text 2 Force of habit is a powerful thing. How else can I explain why I spend $ 200 per month for a package of the Internet, TV, and telephone - most of which I don’t really need My wife and I make most calls on our cell phones. We don’t watch much TV and nearly everything we want we could get online. So why not just pay for the Internet and forget the rest. My answers are totally unreasonable: I’m 49 years old; this is how I’ve always done things; change is hard. Most of the U. S. population is in this same situation. Nielsen recently reported that although online video (视频) viewing has risen 35 percent in the past year, 99 percent of TV viewing is still done on a traditional TV. But that is not the case for younger people, like my friend Dan Frommer, a 27-year-old writer for a Website. Frommer pulled the plug (插座) on cable (有线的) TV in May 2008 and instead gets shows from the Internet by a Macintosh computer connected to his LCD television. He cannot get everthing he’d like to see, but he has saved $ 1,500 on cable-TV bills. The next generation—today’s young people—will likely never sign up for cable TV at all. This is terrible news for cable companies. For decades they have had a wonderful business model, running the tollbooth (收费站) that stood between you and the shows. Now the Internet provides a way to get around the tollbooth, and cable companies are faced with a problem: do they welcome the Internet and try to make money online, or do they fight the Internet and try to delay the damage The answer is to do both: delaying the trend with one hand while racing to develop workable Internet business models with the other. Problem is, even if the tollbooth stays up, it probably won’t make as much money. The rule is that when the Internet hits an industry, wherever you used to make dollars, you now make cents. For cable companies, the good old days may soon be over.
