'You can be sure if it's Westinghouse' was the electrical giant's long-running advertising slogan, made famous by spokesperson Betty Furness in the company's television commercials from the late 1940s through the 1960s. The line became a piece of Americana, quoted and parodied long after the original spots stopped airing. Online it survives as a nostalgic soundbite, dropped into memes and edits whenever a creator wants a joke to carry the weight of old-fashioned corporate certainty.
