Guthy was a pioneer in the use of Infomercials. He was the first to market Infomercials with a brand on the lower left corner of the television screen and he gained success by focusing on quality products and services. His branding and approach helped to differentiate Guthy-Renker from less reputable firms selling on late night television. Guthy was also a pioneer in the use of continuity programs for Infomercials which were very successful for Tony Robbins’ Personal Power books and products.
