What exactly are cookies?
The “what” is known. The “why” is rarely discussed. The term “cookies” has its roots in magic cookies—identification tokens – in UNIX. Web cookies made their appearance in 1994 with Netscape Navigator 0.9 beta—in other words, the beta of the first commercialized web browser. This technology, which was once patented(!) involves data that is placed on a user’s computer in response to a user action. That information can then be read by the site later. It was first designed for use in shopping carts—so that a commercial website would not have to create an ID and store shopping selections unless and until a user decided to buy. Cookies were recognized by Internet Explorer 2 by 1995, they hit the media in 1996 in the Financial Times, and in the same year, the Federal Trade Commission began public hearings on them. Just as they have always been a part of the internet landscape, so have they been controversial.
