Craigslist is a website that provides classified advertisements for various products and services. It was founded in 1995 by Craig Newmark, who wanted to create an online community where people could buy, sell, or trade items with each other. The site has grown significantly since its inception and now includes categories such as housing, jobs, personals, and services. Craigslist is used by millions of people worldwide and provides a convenient way for individuals to connect with others in their local community.
