In 1929 Dickson conducted what ammounts to the first media penetration study. He did a survey for about radio advertising. Broadcast advertising was still very young and many who voiced objections to radio being put to such a use. It was still frequently argued that radio should be a subscription service.
Dickson's survey determined that 90% of the city's radio listeners didn't object to radio commercials. It also stated that almost all respondents claimed to patronized the few advertisers that were then on the air. The results got him blacklisted by every station in town.
Sam Dickson wrote under pseudonyms and for the national syndicators like NBC but in Frisco he was done. Eventually NBC discovered his true identity but his scripts for "Winning of the West" ,were so strong that he was allowed to remain as a staff writer. He continued with NBC as one of its most prominent writers up into the sixties, He also authored the book "SAN FRANCISCO IS YOUR HOME." available Here:
