Rudolph the Red-Nosed Reindeer is a popular Christmas song and character created by Robert May in 1939. The song has since been adapted into several different media, including a television special and an animated movie. Rudolph is typically depicted as a reindeer with a shiny, red nose that glows in the dark, which helps him guide Santa's sleigh through the fog and snow on Christmas Eve. Rudolph has become an iconic figure of the holiday season and is loved by children everywhere.
