The trouble with television is that it
discourages concentration. Television’s variety becomes a narcotic, not a
stimulus. Its serial, kaleidoscopic exposures force us to follow its lead.The
viewer is on a perpetual guided tour: 30 minutes at the museum, 30 at the
cathedral, 30 for a drink, then back on the bus to the next attraction—except on
the television, typically, the spans allotted are on the order of minutes or
seconds, and the chosen delights are more often car crashes and people killing
one another. In short, a lot of television usurps one of the most precious
gifts, the ability to focus your attention yourself, rather than just passively
surrender it. Capturing your attention—and holding it—is the prime motive of most television programming and enhances its role as a profitable advertising vehicle.
