At the age of 16, while still in high school, he began performing at the Comedy Workshop in Houston, Texas. During the 1980s, he toured the United States extensively and made a number of high-profile television appearances; but it was in the UK that he amassed a significant fan base, filling large venues during his 1991 tour. He also achieved a modicum of recognition as a guitarist and songwriter.
Another widely held explanation by the theorists on why Hicks decided to play the character of Alex Jones full time is, well, they say Jones is a CIA disinfo agent put into the AM shock jock scene to discredit actual radio hosts. Here's a portion of a popular blog post explaining it:
Evidence indicates that Bill Hicks transitioned himself into a new 'right wing' talk-radio conspiracy-minded shock jock just as some in government were raising the alarm about Timothy McVeigh 'lone wolf' type domestic terrorists being inspired by AM radio talk jocks. Also it was the advent of the brand-new internet-era and so the timing was perfect to insert a glib provoking-agent into the 'alternative media' scene— someone who could get out front and the lead patriotic Americans around in circles. And so Bill Hicks apparently went to work for the CIA— transforming himself into Alex Jones, the new 'info-warrior'.
In order to become a new man, the theorists posit that he utilized "plastic surgery, testosterone, growth hormone, larynx surgery, and cosmetics." However, the one thing that people freak out about is that Jones and Hicks seemingly have similar teeth (seriously, a lot of work has gone into proving they have the teeth thing,) they have also done vocal comparisons and believe Jones' voice is the same as one Hicks used, at times, in his comedy.
