What was the most televised broadcast in history? The answer to this question is quite surprising. The most televised broadcast in history occurred on December 24, 1968, when the Apollo 8 read from the Bible while orbiting the Earth for the first time. In addition, on December 24, 1979, Russia waged a nine year war against Afghanistan that would deplete their supplies and lead to the collapse of the Soviet Union. December 24 also marks the composition of one of the most famous Christmas songs of all time; Silent Night in 1818 by an Austrian composer. The last major event that occurred on December 24th, this time in 1923, was President Coolidge's lighting of the first public Christmas tree.
