The Reader:

"Who is this elusive creature, the reader? The reader is someone with an attention span of about 30 seconds—a person assailed by many forces competing for attention. At one time those forces were relatively few: newspapers, magazines, radio, spouse, children, pets. Today they also include a "home entertainment center" (television, VCR, tapes, CDs), e-mail, the Internet, the cellular phone, the fax machine, a fitness program, a pool, a lawn, and that most potent of competitors, sleep."
