Tweedle joined Bonneville in April 1973, the first month a designated hitter was used in Major League Baseball and the first handheld cellphone call was made. Tweedle remained with Bonneville for the next 37 years, and will leave as SVP. Tweedle is a current member of the Media Rating Council Board of Directors, chair of the NAB COLRAM Committee and past member and chair of the Arbitron Radio Advisory Council. He tells friends via email "I worked with an amazing group of folks through my years at Bonneville. I have the greatest respect for my colleagues, recent and past, and have learned much from them."
