推断题。由题干中的viewer's expectations定位至第四段。倒数第二句指出“As a result,viewers’expectations have changed dramatically.”,之前提到的原因是“Video-cassette recorders have been replaced by DVD players and digital video recorders(DVRs),both of which are easier to use.Cable and satellite firms offer a growing number of videos on demand.TV has gone online and become mobile.”,这些都属于技术进步范畴,故[A]为答案。文中没有提到娱乐活动的丰富性,互联网的传播和节目数量问题,排除其余三项。
