YMMV / Die Sendung mit der Maus

• Iconic Character, Forgotten Title: The show's original title was Lach- und Sachgeschichten für Fernsehanfänger (roughly: Stories for Laughing and Learning for TV Beginners). But after the orange mouse was introduced, everyone called it just "the programme with the mouse". (The "Lach- und Sachgeschichten" part of the old title is still present in the title segment though).
• Periphery Demographic: According to demographic polling, the average fan may be as old as the show. The creators have noted a trend wherein as kids become teenagers they decide they're too old to watch, then rediscover it via adult nostalgia.
