In the 1930’s research was conducted showing that the average person is most in need of an energy boost at 10:30 a.m., 2:30 p.m., and 4:30 p.m. After a contest was held to come up with an advertising slogan the winner was “Drink a bite to eat at 10, 2, and 4”. Many of Dr. Pepper’s advertisements after that featured the “10, 2, 4” slogan in varying forms until the slogan changed in the 1950’s.
