A more modern form of the EPG, associated with both television and radio broadcasting, is the interactive [electronic] program guide (IPG, though often referred to as EPG).
An IPG allows television viewers and radio listeners to navigate scheduling information menus interactively, selecting and discovering programming by time, title, channel or genre using an input device such as a keypad, computer keyboard or television remote control.
Some guides also feature backward scrolling to promote their catch up content. Non-interactive electronic program guides (sometimes known as "navigation software") are typically available for television and radio, and consist of a digitally displayed, non-interactive menu of program scheduling information shown by a cable or satellite television provider to its viewers on a dedicated channel.In 1859 a major break occurred between the two American Tract Societies, due to a difference of opinion over the issue of whether or not to publish tracts which concerned "the sin of slavery." The American Tract Society (Boston, Mass.) continued to publish and distribute tracts under the name "American Tract Society." The New York-based American Tract Society promptly (1859) opened a New England Branch in Boston; they also operated major branches in Rochester, N.Y.; Cincinnati, Ohio; and Chicago, Ill., and secondary New York city branch.EPGs are transmitted by specialized video character generation (CG) equipment housed within each such provider's central headend facility.By tuning into an EPG channel, a menu is displayed that lists current and upcoming television programs on all available channels.
