For some, hating commercialism used to mean rolling their eyes with the interruption of Friends. And now, some might think it means shaking their fist at pop-up ads. But a team of UK street artists have taken it to the next level. Brandalism is a crew of rabble-rousers who began projects in anti-advertising out of Britain a couple years back. They’ve since elevated the idea of taking back the streets to a whole new echelon, reclaiming the public sphere from corporate entities in what they are claiming is the largest advertising takeover in world history. Following in the guerilla art traditions of the 20th Century (and taking inspiration from Agitprop, Situationist and Street Art movements), Brandalism’s most recent campaign this month delivered the work of 40 international artists to 360 corporate advertising spaces throughout 10 UK cities, accomplished in just two days. See the full artist list here. Want to launch an anti-Clear Channel campaign of your own? Start with this guide. Unless, that is, your idea of brandalism is defacing your own wall with high-couture branding. But that’s a little too easy, ain’t it?
