Craigslist.org was created back in the mid-1995s, when most U.S. users got access to the Internet. The creators realized that people would use the World Wide Web for searching and posting various information, including classifieds. They have started with the idea to create a handy, cheap, affordable and concise website for placing such ads.To this day, Craigslist kept the same format with categories and various ads viewed on a white background. When navigating the ads, you can specify search parameters and find the options, which are most suited to you. Initially, this site was mainly used to post resumes and job advertisements, but with time, they were diversified with offers for rent and sale of real estate, other products, and even personals.
