On-line Advertising Revenues |
 |
Although Internet advertising only really started in 1994, revenues showed a steady and fast growth. In 1997 US$ 906.5 million were spent on on-line advertising. Compared with advertising revenue for the television industry in equivalent dollars for its third year, the Internet was slightly ahead, at US$ 907 million compared to television's US$ 834 million. 1998 on-line advertising grew by 112 percent to US$ 1.92 billion in revenues, and is on track to hit US$ 4 billion in 1999, which would put Internet advertising at about 2 percent of the U.S. ad market.
