By September 2008 Craigslist was the leading classified advertising service worldwide. It provided free local classifieds and forums for more than 550 cities in over 50 countries, generating more than 12 billion page views per month, used by more than 50 million people each month. Craigslist users self-published more than 30 million new classified ads each month and more than 2 million new job listings each month. Each month Craigslist also posted more than 100 million user postings in more than 100 topical forms. All of this it did with only 25 employees.
Because Craigslist did not charge for classified advertising it replaced a large portion of the classified advertising that historically was placed in print newspapers. By doing so it substantially reduced the significant revenue that print newspapers historically generated from classified advertising. This contributed to an overall reduction of profits for many print newspapers. Similarly, Craigslist's policy of charging below-market rates for job listings impacted that traditional source of newspaper revenue, and impacted profits at physical employment agencies, and the more expensive online employment agencies.
