Joe St. Lawrence started RTM, the industry's first production company for auto how-to shows in the mid-1980s. He created PowerBlock, television’s first two-hour, auto theme-block featuring how-to shows that introduced SEMA-member products to million of viewers. St. Lawrence’s shows sparked parts-buying on Monday, and gave DYIers the confidence to bolt-on aftermarket parts and customize their vehicles. He introduced broad audiences to cool cars and helped change the image of the backyard mechanic into a tool-wielding expert.
