- The Trope Maker that spawned a thousand other Shoot’Em Ups, Space Invaders debuted in 1978. Although Pong had started the industry, this game revolutionized it, virtually launching The Golden Age of Video Games, establishing or codifying many of the tropes used in later games, such as Video Game Lives, and a separate score counter for high scores.

The Montlake Bridge spanning the Montlake Cut in Seattle was completed in 1925, the last-built and easternmost of four double-leaf bascule bridges that carry vehicle and pedestrian traffic across the Lake Washington Ship Canal. It is set apart from its sister bridges by both its Gothic architectural details and its mechanical design, and has been listed on the National Register of Historic Places since 1982.
