Blue! 42! How helmet radio changed the NFL

For decades, NFL strategy slowly evolved from each team running a dozen different plays, to rigid schemes with coaches sending in orders through codewords and secret signals. Then, one piece of audio technology revolutionized the game. Beginning in the early 1990's, the NFL allowed coaches to speak directly to their quarterbacks through radios in their helmets. What followed was an instant increase in excitement for the nation's most popular sport, spawning a high-scoring era of fast paced offenses.
