In its strictest sense, a celebrity chef is a someone who has become well-known for his/her cooking. The first historical personality that fits this escription is Martino da Como but in practical terms the term grew in popularity during the 1990s. It accompanied an explosion in popularity of cookery programmes on television and cookery features in the printed press. The name celebrity chef is sometimes used in a slightly derogatory way - a celebrity chef who has "sold out" to the media being seen as somehow inferior to a traditional chef in a restaurant.
