A telestrator is a device that allows its operator to draw a freehand sketch over a motion picture image.

[edit] History

The telestrator was invented by physicist Leonard Reiffel, who used it to draw illustrations on a series of science shows he did for public television in the late 1950s. The user interface for early telestrators required the user to draw on a TV screen with a light pen, whereas modern implementations are commonly controlled with a touch screen or tablet PC.

Today telestrators are widely used in broadcasts of all major sports. They have also become a useful tool in televised weather reports.

According to Fox Sports, a telestrator costs around $12,000.
