Encyclopædia Britannica Buys Wikipedia    (April Fool's Day - 2005)

Wikipedia announced it was being taken over by Encyclopædia Britannica, in exchange for a £133.7 million severance package given to each of the five trustees of the Wikimedia Foundation.

One of the first changes was that Wikipedia would henceforward be spelled Wikipædia. In addition, users would be charged £99.97 to create or edit a page.
