As of 2012, mashup sites such as and were overlaying Craigslist data with Google Maps and adding their own search filters to improve usability.
In June 2012, Craigslist changed its terms of service to disallow the practice. The site is considered particularly useful by lesbians and gay men seeking to make connections, because of the service's free and open nature and because of the difficulty of otherwise finding each other in more conservative areas.
It became a web-based service in 1996 and expanded into other classified categories. Having observed people helping one another in friendly, social, and trusting communal ways on the Internet via the WELL, Mind Vox and Usenet, and feeling isolated as a relative newcomer to San Francisco, Craigslist founder Craig Newmark decided to create something similar for local events.
In early 1995, he began an email distribution list to friends.
Most of the early postings were submitted by Newmark and were notices of social events of interest to software and Internet developers living and working in the San Francisco Bay Area. The number of subscribers and postings grew rapidly.
There was no moderation and Newmark was surprised when people started using the mailing list for non-event postings.
The site received criticism and complaints from attorneys general that the section's ads were facilitating prostitution and child sex trafficking.
Matt Zimmerman, senior staff attorney for the Electronic Frontier Foundation, said, "Craigslist isn't legally culpable for these posts, but the public pressure has increased and Craigslist is a small company." Brian Carver, attorney and assistant professor at UC Berkeley, said that legal threats could have a chilling effect on online expression.
The company does not formally disclose financial or ownership information.

The initial technology encountered some limits, so by Majordomo had been installed and the mailing list "Craigslist" resumed operations.
