Johnson was the founder, president, and CEO of Agri Communicators Inc., which included the Agri Broadcasting Network (ABN Radio), Ohio's Country Journal, a monthly farm newspaper, and the television program AgriCountry.
The network evolved out of Johnson's daily reports aired on Columbus radio station WRFD from 1967 to 1972.
In 1972, he started the ABN and his daily reports were eventually broadcast to over 72 radio stations across Ohio, Indiana, and West Virginia.
Known for his infectious enthusiasm and passion for agriculture, Johnson always opened his broadcast with the trademark phrase "From the Farm, Good Morning!
Johnson was honored posthumously for his work by the National Association of Farm Broadcasting in 2005 with enshrinement in the NAFB Hall of Fame.
