In June 1994 Louis J. "Lou" Montulli II at Netscape Communications Corporation invented the HTTP cookie.
"The introduction of cookies was not widely known to the public, at the time. In particular, cookies were accepted by default, and users were not notified of the presence of cookies. Some people were aware of the existence of cookies as early as the first quarter of 1995, but the general public learned about them after the Financial Times published an article about them on February 12, 1996. In the same year, cookies received lot of media attention, especially because of potential privacy implications. Cookies were discussed in two U.S. Federal Trade Commission hearings in 1996 and 1997" (Wikipedia article on HTTP cookie, accessed 05-09-2009).
