called a “word-cross” puzzle in the “Fun” supplement of the Sunday edition of the
New York World. It was the first crossword puzzle to be published. The name was
later changed to “crossword” and became a regular weekly feature in the World

Instant replay is the replaying of video footage of an event such as a televised
sports program in which an important or remarkable play may be seen again or
be reviewed if it was unclear on first sight. A CBS television director, 29- year-old
Tony Verna (above), invented the system which enabled a standard videotape
machine to instantly replay. It was used for the first time on 7 December 1963,
for the network’s coverage of the 64th annual  Army-Navy football game.
