When I was a teenager living in Los Angeles in the 1960's, I used to listen to AM radio quite a bit at night. During that time, I often listened to a couple of stations, KABC and KLAC. Some of the personalities on those stations were Joe Pyne, Michael Jackson (no relation to the pop musician), Mort Sahl (the comedian), Joel Spivak, and others. These men all conducted talk radio shows which at the time were referred to as "two-way radio". Talk radio actually started before the 1960's on the east coast; some of the personalities involved with it came west after beginning their careers in the east.
One of my favorite radio talk show hosts of the 1960's was Joe Pyne. Pyne was a Marine Corps veteran of WW2. His on-air style was informative and argumentative. He didn't suffer fools gladly, and would often insult callers with phrases such as, "Ah, go gargle with razor blades" and "What's your point beside your head?" Basically a conservative, he would end his shows with the phrase, "Straight ahead and get Castro." He died in his forties of lung cancer at the height of his career in 1970.
Joe Pyne also had a TV show on KTTV in Los Angeles that was later nationally syndicated. You can look on Youtube and find video clips of a few of Joe Pyne's shows that were broadcast.
Anybody remember the American Nazi Party of the 1960's? The leader of the American Nazis was George Lincoln Rockwell. I don't know how serious Rockwell was about being a Nazi in America, but his timing for promoting the cause was somewhat off, as the 1960's were not particularly a time of economic turmoil. There was racial turmoil, and Rockwell later made some political hay out of that. Nevertheless, the American Nazis never had more than a few dozen actual members and perhaps a few hundred sympathyzers.
Joe Pyne used to have ripe comments re. the American Nazis, whom he called "American Nutsies". Their leader, George Lincoln Rockwell, he called "George Stinkin' Ratwell".
