TV Guide
To save page space, "TV Guide" incorporated a grid (a rowed display of listings for programs scheduled to air during the evening hours each night, primarily organized by channel) into the listings in September 1981, which was slotted at a random page within each day's afternoon listings. The grid originated as a single-page feature that provided a summary of programs airing during prime time (from 7:00 to 10:00 p.m. or 8:00 to 11:00 p.m. depending on the start of prime time within a given time zone) on the stations mentioned in the corresponding edition; by 1985, it was expanded to a two-page section – which began to take up roughly three-quarters of the two adjoining pages on which it was placed – that included programs airing during the early access and late fringe periods (from 5:00 to 11:00 p.m. or 6:00 p.m. to 12:00 a.m. local time), with the beginning and end of the magazine-defined prime time daypart (between 7:30 and 11:00 p.m. or between 6:30 and 10:00 p.m. local time on Monday through Saturdays, and between 7:00 and 11:00 p.m. or between 6:00 and 10:00 p.m. local time on Sundays) delineated by a thicker border. Channels listed in the grid were organized by broadcast stations, basic cable channels, and premium channels.
