Craigslist, a simple web listing service, can now be found in 100 cities worldwide. It is a Web-based platform that has greatly impacted the world of classified advertising. Craig Newmark started the business as an email list that he sent to a small group of friends back in 1995. He was working at Charles Schwab and then later as a software contractor.
He’d hear about events around San Francisco that he wanted others to know about and started sending the emails along. The page views are now in the millions. There are fewer than 20 people who work at the company. Today, Craigslist is one of the world’s ten most-visited English-language websites.
