History JGI Outdoor Advertising


Mr. John P. Gannon, the owner of JGI Outdoor Advertising, has been in the billboard business for almost thirty years. In 1994, John began JGI Outdoor with an acquisition of forty billboards. Well, by December 2002 those forty billboards had quickly turned into over seven hundred billboards in Houston and its surrounding areas, along I-10 from Houston to San Antonio, and along the I-35 corridor between, in, and around the cities of New Braunfels and San Marcos.
