The first drive-in movie theatre opened in New Jersey on June 6, 1933. A patent had been awarded the previous month to chemical company magnate Richard M. Hollingshead, Jr. He advertised his drive-in theater with the slogan, "The whole family is welcome, regardless of how noisy the children are". Entrance cost 25 cents a car and 25 cents a person. YouTube has a number of videos featuring a montage of the ads shown during interval – a vital component of the experience since it brought in revenues from visits to the snack bar or concessions stand. My mother would pack supper – mashed pilchard and mayonnaise sandwiches – in a cake tin, so we were very seldom treated to the junk food they offered. Reminiscing YouTube viewers, in response to the vintage commercials, recall drive-in intervals with fondness, probably because it was synonymous with food: "My parents could never understand why these were my favorite part of the Drive-In movie program". Another's response is more philosophical: "I wish it was still like this now ... things were so much better and the men respected the women ... and the same for the women now its the total opposite its sad then theres the economy."
