The Golf Channel, for instance, is watched by people who play golf； Home and Garden Television is seen by those interested in household improvement projects. Thus, audiences are smaller and more homogeneous than they have been in the past. Second, there is an increase in the number of television channels available to viewers, and thus, advertisers. This has also resulted in an increase in the sheer number of advertisements to which audiences are exposed. Third, digital recording devices allow audience members more control over which mercials they watch. Fourth, control over programming is being passed from the works to local cable operators and satellite programmers. Newspapers After television, the medium attracting the next largest annual ad revenue is newspapers. The New York Times, which reaches a national audience, accounts for $ 1 billion in ad revenue annually. It has increased its national circulation(發(fā)行量 ) by 40% and is now available for home delivery in 168 cities. Locally, newspapers are the largest advertising medium. Newspapers are a less expensive advertising medium than television and provide a way for advertisers to municate a longer, more detailed message to their audience than they can through television. Given new production techniques, advertisements can be printed in newspapers in about 48 hours, meaning newspapers are also a quick way of getting the message out. Newspapers are often the most important form of news for a local munity, and they develop a high degree of loyalty from local readers. Radio Advertising on radio continues to grow. Radio is often used in conjunction with outdoor billboards(廣告牌 ) and the Inter to reach even more customers than television. Advertisers are likely to use radio because it is a less expensive medium than television, which means advertisers can afford to repeat their ads often. Inter panies are also turning to radio advertising. Radio provides a way for advertisers to municate with audience members at all times of the day. Consumers listen to radio on their way to school or work, at work, on the way home, and in the evening hours. Two major changes—satellite and Inter radio—will force radio advertisers to adapt their methods. Both of these radio forms allow listeners to tune in stations that are more distant than the local stations they could receive in the past. As a result, radio will increasingly attract target audiences who live many miles apart.
