Just learned this:  In 1915, William Wrigley mailed a complimentary four-stick package of gum to every household in the United States that owned a telephone. 

People with telephones, he reasoned, could afford gum.

This helped to sustain Wrigley’s gum as an established national brand.  And this made Wrigley very rich, particularly after he took his company public in 1919.

WHAT MIGHT MEDIA COMPOSERS TAKE FROM THIS 100-YEAR OLD CAMPAIGN?
