The first episode of Mad Men alludes to Bernays work. They are trying to come up with a new campaign for Lucky Strike and he rejects an idea to base the campaign off of Freud’s research.
The campaign that Draper landed on, "It's Toasted", was actually created around 1917 or so I believe. Bit of an anachronism there.
Other interesting campaigns in the show: VW's bug, Kodak's Carousel, and of course the Coca-Cola ad at the very end. Truly wonderful show.
