Satan and savior

"During the early years of American television, the cultural preeminence of mainline Protestantism was a given. Evangelicalism and fundamentalism, if acknowledged at all, were portrayed as dinosaurs on their way to extinction. Yet by 1980, the equation changed. Televangelists eclipsed mainline broadcasters, even though the latter entered the television age with the cultural and economic advantages. This book compares the mainline and evangelical Protestant responses to television, with an eye toward understanding the long-term consequences in the political, cultural, and religious spheres."--Jacket.
