One of the interesting web phenomena of recent years has been the rise of the Hitler meme on YouTube.
In these, a clip from the film Downfall (2004)is used repeatedly, but with a range of subtitles added.
The idea combines a mixture of humiliating the demonic figure that Hitler represents, while also displaying the prowess at comedy writing and timing of the producer, who uses a raging Hitler as the platform for social satire.
Some work better than others, and the choice of subject matter can make for uncomfortable viewing.
The Guardian newspaper has produced a good article that explores this phenomenon. It's a good reminder that in an age where we're all media producers, popular content and the means of its distribution don't necessarily reside with the ruling elites of old. What makes it fascinating for media educators and observers like myself, is the fact that the old rules don't apply, and market forces are taking on a whole new dynamic.
