*License Exam Quiz #288*

The quiz this week will be random, but first a reminiscence through some
radio history. Radio is a relatively new thing to the average consumer,
having been only about 100 years since it first entered our lives. Today we
use radios that most people do not realize are radios (those being cell
phones, to ensure we are all in the know). Marconi’s first transmissions,
Roosevelt’s Fireside Chats, my parents as children eagerly awaiting their
favorite radio programs… I’ll leave you with one more historic radio
moment. It was 1951 and the Brooklyn Dodgers were playing the New York
Giants for the National League Pennant. These, by some estimates, were the
first nationally broadcast games. On October 3rd, a three run home run gave
the Giants the come-from-behind win with the announcer Russ Hodges
exclaiming “The Giants win the pennant” four times. This was the call on
the radio broadcast, although it is often played over the television
broadcast where the call was “Thompson swings...it’s gone” according to
baseballhall.org
