Originally a weekday two-hour program from 7-9 a.m., it expanded to Sundays in 1987 and Saturdays in 1992. The weekday broadcast expanded to three hours in 2000, and to four hours in 2007 (though over time, the third and fourth hours essentially became their own distinct entities). Today's dominance was virtually unchallenged by the other networks.[IMAGE: https://steemitimages.com/DQmcjtNoeH9DXonqgU49LLozJiFyoHrJ8s8Q8qiPxu41bjA/4517BE73-7453-4E30-9024-D57444EE3D06.jpg]
