2. Apple's "Lemmings"
One year after releasing its remarkable 1984 ad campaign, Apple put together this morbid “Macintosh Office” spot demonstrating a cult of office workers submissively walking off a cliff. Critics panned the ad for its depressing motif, IT workers, the very people they were trying to sell on their products, found it insulting, and children were terrified of it. Apple should have kept this one in the vault.
