TV cooking programs brought the recipes of cooks to a new audience who wanted to try out new ways of cooking. In the early days, the recipes were available by post from the BBC and later with the introduction of the CEEFAX text on screen system, they became available on the television. The new companies of Channel 4 and S4C also brought recipes to the television with their own text system called ORACLE. Today the television is still a major source of recipe information, with world-wide cooks and chefs such as Julia Child, Jamie Oliver, Nigella Lawson and Rachael Ray having TV shows and websites giving the details of all their recipes.
