In 1978, KMPH launched its news department and began producing a nightly primetime newscast Monday through Friday; "The 10 O'Clock News". Originally the station sourced its national news from the ITN Satellite News Service and API Wire Services to augment its own local news coverage, primarily split between the cities of Visalia and Fresno and the surrounding communities. In late 1979, KMPH launched a short-lived midday newscast, "The Midday Edition", which was cancelled after nine months. Later, in the early 1980s, the station's newscast was expanded to Saturdays. In early 1982, KMPH, launched a weekly newsmagazine show, "The Sunday Edition", which occupied the 10 p.m. timeslot on Sunday nights; it was cancelled a year later. "The 10 O'Clock News" went on to become the longest-running primetime newscast in the Fresno market. On October 6, 2003, KMPH debuted a three-hour weekday morning newscast, titled "Great Day"; that same date, the station also launched a half-hour midday newscast at 11:30 a.m. In the spring of 2007, "Great Day" was expanded to five hours, running from 5-10 a.m.
