Prologue

In the 1980s and early 1990s, traditional media, like TV, radio, and print were the dominant source of news and information. The Internet changed all that with the onset of computers, servers, browser-technology, and Internet Service Providers (ISPs). As consumers migrated to online sites for news, information, and shopping, offline publishers, who earned their revenue from selling advertising slots to advertisers, began migrating to online publishing formats. In like manner, advertisers had to migrate to online sites to reach their target consumers.
