What Surprising Movie Feature Was First Introduced in the 1980s?

One of the most interesting developments in the movie industry occurred in the 1980s with the introduction of the "post-credits scene." While the concept of including additional footage after the credits had been seen in earlier films, it became popularized by Marvel Comics' animated films and later, notably, by "The Breakfast Club" in 1985. This innovative feature not only served as a humorous epilogue but also encouraged audiences to stay seated, creating a sense of anticipation and engagement with the film's universe. Over the years, this trend has evolved, becoming a staple in blockbuster franchises, particularly in the Marvel Cinematic Universe, where post-credits scenes often tease future films or provide humorous callbacks, contributing to a richer cinematic experience and enhancing audience loyalty.
