In 1985, he created his first infomercial after identifying an opportunity to fill the late-night and early-morning dead air time on cable networks. While companies like Vitamix had been producing infomercial programs for TV broadcasters since 1949, Harrington's model of replacing the time that the broadcaster was normally off the air with entertaining and informative advertising launched the modern infomercial format.
