* HeyItsThatGuy: Bill Cullen had already been known and respected as a game show legend by the time ''Blockbusters'' rolled around, while Bill Rafferty was known for ''Every Second Counts'' and ''Series/CardSharks'', the latter of which he was doing at the same time as this series.
* HeyItsThatSound: The original BonusRound timer was recycled on ''Series/{{Concentration}}''.
* TechnologyMarchesOn: When the UK version first started, all contestants received a dictionary (later an encyclopedia). Now, everyone who plays wins an E-book reader.
** Not unlike ''Series/{{Concentration}}'' , the Raffety version updated the board with computer graphics.
