Tote board

A tote board (or totalisator/totalizator) is a numeric or alphanumeric display used to convey information, typically at a race track (to display the odds or payoffs for each horse) or at a telethon (to display the total amount donated to the charitable organization sponsoring the event).

The term "tote board" comes from the colloquialism for "totalizator" (or "totalisator"), the name for the automated system which runs parimutuel betting, calculating payoff odds, displaying them, and producing tickets based on incoming bets.
