What it is

Lou Montulli devised at Netscape a mechanism for servers to store small pieces of data in the user's browser, solving the problem of maintaining state (such as a shopping cart) in the HTTP protocol, which has no memory between requests.

Montulli and John Giannandrea wrote the first specification in 1994; Netscape Navigator 0.9beta (October 1994) was the first browser to support cookies.

What it led to

  • user sessions and shopping carts in e-commerce
  • web tracking and advertising profiling
  • privacy regulations, such as the European GDPR, on cookie use
