I just saw a great ad on Shockwave.com with a limp joystick asking "Is spyware affecting your performance?" Hilarious. Nice job whoever did it for McAfee.
And I'd love to have reposted that ad on this blog... and I suppose get paid for it.. but regardless, why should video be the only form of viral advertising. Every single ad element out there should be sharable. Where's the embed code for this ad? Even if you don't build in a way to pay me, people don't get paid to pass YouTube videos around (for the most part) yet either... so why shouldn't you be making banner ads that are just as entertaining and just as worth playing?
