Homestar Runner is a Flash animated internet cartoon series. It mixes surreal humor with references to retro pop culture, notably video games, classic television, and popular music.
The cartoons are normally centered on the title character, Homestar Runner. However, a series titled Strong Bad Email or sbemail, in which another main character, Strong Bad, answers emails from viewers, is the most popular and prominent feature of the site. While Homestar and Strong Bad are the main characters, the site has grown to encompass dozens of other characters over the years.
The site is one of the most visited sites with collections of Flash cartoons on the Internet and is notable for its refusal to sell advertising space (the creators pay for everything through merchandise sales, which includes a line of T-shirts). The owners of the website had turned down offers to make a television series.
The site's popularity spread via word of mouth. Its popularity has declined in recent years, with no new content released since December 2010.
