When C-SPAN's cameras came to Congress in 1979, a wave of bloodless guerrilla maneuvers followed. Newt Gingrich, in those days a brash young Georgia congressman, led an insurgent cell of Republicans looking for ways to make the cameras work for them. One of their techniques was to deliver so-called "special order" speeches when the day's business was over, which in addition to airing live on cable could be shared with local channels back home.
"These speeches frequently called out the Democratic opposition directly, daring them to respond," the Purdue historian Kathryn Cramer Brownell writes in 24/7 Politics, a new history of cable news and the regulatory forces that shaped it. "But nobody did," she adds, "because the legislative session had ended and everyone was gone." Not that you could tell that by watching the show, since the camera's eye stayed fixed on the person speaking.
