A TV tray table is a small folding table that is easily opened or closed to allow users to simply set up or take down the table quickly and easily. They are also sometimes called a personal table, a TV dinner tray, or a tray table.
TV tray tables rose to prominence in the 1950s along with the popular habit of watching television and eating and at the same time. At that time many Americans enjoyed eating TV dinners on the tables. In some households, each person in the family has their own personal table so that the entire family can eat and watch TV together.
