Homestuck is the longest webcomic on the internet.
While nominally a webcomic, Homestuck consists of a combination of static images, animated GIFs, and instant message logs. Generally, pages included a single panel, and navigational links to successive pages are phrased similarly to commands in interactive fiction games. Additionally, unlike previous works from Andrew Hussie which exclusively relied on GIF images for animation, Homestuck introduced complex animations and browser games made with Adobe Flash, many involving contributions from fan artists.
