A 1957 ad for TV tray sets in a variety of styles and colors. These Cal-Dark Roll-a-Tray TV tray table sets are, according to the ad, "The handiest thing around the house...(next to a husband)" I'm sure there are many women who would disagree with that one. TV trays were very common back in the 1950s and continue to be today. I had a number of friends who grew up eating dinner at the dinner table only when they had company. Otherwise, they ate at the TV.
