A cleverly promoted mascot can do wonders for a company. Just look at what JACK did for JACK IN THE BOX. Jack was reinvented when Jack In The Box fast food restaurants were at the brink of extinction. In 1993, Jack In The Box's undercooked hamburgers led to an e.coli outbreak that caused the death of 4 customers and left several hundred sick. In 1994, the revamped Jack mascot was introduced as the spokesperson for Jack In The Box. He had a dramatic impact on the general public's trust and support for the restaurant chain. Here are two of my favorite Jack commercials.
