Switching channels

摘要

One of the most popular television shows in America this autumn is called "How to Get Away with Murder", about a law professor and her students, who become involved in a mysterious killing. Most cable subscribers will find the title an appropriate description of their viewing experience. Couch potatoes are forced to spend around $90 a month for their subscription. They receive over 160 channels, most of which they skip straight past. By one estimate the cost of a cable subscription has more than doubled since 2000. All that for the privilege of doing business with companies that consistently rank in the lower regions of customer-satisfaction surveys.
