The North American broadcast television frequencies are on designated television channels numbered 2 through 69, approximately between 54 and 806 MHz. Traditionally, the frequencies are divided into two sections, the very high frequency (VHF) band and the ultra high frequency (UHF) band. The VHF band is further subdivided into two more sections, VHF-Lo (band I) and VHF-Hi (band III). In between lie allocations for other services including the FM broadcast band (band II), bands used for land mobile radio, radio remote control, civil service agencies, amateur radio, and aircraft navigation aids and voice communication (airband).

—Edward Dahlberg (1900–1977)
“Listening to a news broadcast is like smoking a cigarette and crushing the butt in the ashtray.”

“They [parents] can help the children work out schedules for homework, play, and television that minimize the conflicts involved in what to do first. They can offer moral support and encouragement to persist, to try again, to struggle for understanding and mastery. And they can share a child’s pleasure in mastery and accomplishment. But they must not do the job for the children.”
—Dorothy H. Cohen (20th century)
