"It"s time to realize TV must be doing something right to reach and affect so many people and that teleliteracy is something to be quantified and upgraded and utilized, not ignored," David Bianculli declares in his defense of teleliteracy--the widespread knowledge of television that ties Americans together in ways other media cannot. He acknowledges the faults of television -- sex and violence to a widespread audience -- but contends that TV has delivered positive role models, good storytelling and likable characters. Bianculli, a television critic for The New York Post and The Philadelphia Inquirer, offers an interesting defense of a much-maligned medium.
