Stuart Brown's fantastic YouTube series A Brief History Of Graphics starts in just about the most perfect way imaginable: "They say graphics aren't important... but every game I've ever played has had them".
Running over five parts, the series takes an in-depth (but also accessible) look at the evolution of video game graphics, from the very beginnings of the medium through to today's complex 3D visuals.
If you care at all about the history of video games, or even just want to learn exactly how things have evolved (and what some of the most important titles have been), it's a must-watch.
Note that only episodes 1-4 are available. Episode 5 should be out tomorrow.
