- "...right opposite them, almost at Harry's eye level, was a gigantic blackboard. Gold writing kept dashing across it as though an invisible giant's hand were scrawling upon the blackboard and then wiping it off again; watching it, Harry saw that it was flashing advertisements across the field."
This blackboard was part of the Quidditch Trillenium Stadium built for the finals of the 1994 Quidditch World Cup. It was located directly opposite the Top Box, almost at eye level of those seated in it. The blackboard was enchanted to display messages in golden handwriting. Prior to the game, it was used to display advertisments for various products, such as the Bluebottle and Bertie Bott's Every Flavour Beans. Once the final began, the board was converted into a scoreboard.
