This inclusion may come as a surprise! Your response to seeing it on the list was probably, “Oh wow!” A non-profit website, Wikipedia is an online library that puts well-founded data at the world’s fingertips. Its information is donated by unnamed, online sources. Wikipedia is mainly funded with monetary gifts from its readers around the world.
In addition to this, it uses the proceeds from its online store. Ironically, sales make up a small percentage of revenue for the online encyclopedia, which is hosted by Wikimedia. Its host company puts a lot of effort into its fundraising programs to keep the free site operating.
