Radio personalities were expected to participate in promotions and make personal appearances. Morton's relaxed style – he was known to occasionally mutter and talk to himself on the air in an endearing way – and his delight in making people laugh made him an audience favorite. Besides playing records, personalities spent a lot of air-time talking about traffic, news, and weather as well as cracking jokes and providing listeners with friendly companionship. KVI was a successful MOR station, which stood for middle of the road. His job title was "radio personality" as well as disc jockey. In 1964 Morton became the station's evening man and soon won over listeners with his witty banter. (The marriage later ended in divorce.)

From 1941 to 1947, young Jack lived in California when the elder Morton worked for CBS there. His mother, Clara Huggins Morton, was the granddaughter of a British Hudson's Bay Company fur trader who in 1849 arrived in what would later become Washington state.

His father Archie was a Puget Sound broadcasting executive. John Archibald Morton was born in Seattle on February 13, 1935. During his decades-long career, radio broadcasting saw a lot of changes, and Morton navigated them with grace, charm, and wit. When he made personal appearances and when he engaged in wacky public stunts, listeners were happy to come see him in person. Disc jockeys were celebrities and Morton was one of the biggest. Beginning in the early 1960s, Seattle-area radio listeners enjoyed the company of the amiable Jack Morton at home, in their cars, and at the beach on transistor radios.
