判断题Until the Late 1940s, when television began finding its way into American homes, companies relied mainly on print and radio to promote their products and services. The advent of television brought about a revolution in promoting products and services. Between 1949 and 1951, advertising on television grew 960 percent. Today the Internet is once again transforming promotion. By going online, companies can communicate instantly and directly with prospective customers. Promotion on the World Wide Web includes advertising, sponsorships and sales promotions like contests and coupons. In 1996, World Wide Web advertising revenues reached $300 million.

Although organizations like Nielsen Media Research are developing technologies to enhance audience measurement and tracking, it remains difficult to assess how many times the same person looks at an ad and who that person is. Although online promotions can be glamorous and sophisticated, they are not perfect. For a well-designed marketing mix, industry experts advise companies to use the Internet as a supplement to other advertising media.
