Adbusters magazine editor Kalle Lasn created the hashtag #occupywallstreet on July 13 to "tap simmering frustration on the American political left." He intended to create a message that would capture and define a moment and a movement.

“There’s a number of ways to wage a meme war,” Mr. Lasn, whose name is pronounced KAL-luh LAS-en, said in an interview. … “If you’re able to come up with a very sexy sounding hash tag like we did for Occupy Wall Street, and you come up with a very magical looking poster that seems to have something very profound about it, these devices push these memes, these meta memes, into the public imagination in a very powerful way,” he said. … “This is what Adbusters has done for the past 20 years, to come up with these memes and to propagate them,” he said. “That’s what it’s all about: may the best memes win.”
