What makes for a great viral marketing campaign? The answer appears to be babies and impressive tricks. As part of software developers Ubisoft and the launch of their cool new guitar video game Rocksmith, they have created one of the most realistic prank ads I have ever seen. This ingenious piece of viral marketing and special effects makes the e-Trade and dancing Evian babies look archaic in comparison. Like a great illusionist, the spot's use of clever edits and simple youtube style camera work help sell the elaborate hoax.
