Wikipedia is a non-profit, free-access Internet encyclopedia, with over 38 million pages in many different languages that are created by staff members and basically anyone who can.
Wikipedia was founded on January 15, 2001 by Jimmy Wales and Larry Sanger. It eventually became the 5th most popular Internet website, thought it’s now at number 7.
Wikipedia celebrated its 15th anniversary this year! I find it very helpful, for I have my own Wikipedia account, but it is criticized for letting anyone and everyone edit its pages. This can result in false information.
Even with its faults, Wikipedia is a very useful website, and I am not alone in saying that I hope Wikipedia will last 15 more years at least!
