researcher, claimed that patrons at a
movie theater in were shown two
advertising messages, Eat Popcorn
and Drink Coca-Cola, while they
watched a film. The message was
flashed for 3/1000 of a second once
every five seconds, but the duration
of the messages was so short that

perceived by the viewers. Over the
