How can you drive consumers to become evangelists for your product online, with a limited budget? Chemistri developed a viral marketing campaign for Heinz Tomato Ketchup that has created a cult following across the U.S. and Europe. The campaign is called "Splirt." "Splirt" is a propietary Shockwave-enhanced e-greeting engine that teens can use to send a messy, ketchup-dripping, personalised message to their friends and family. To start the mayhem, the user must go to www.splirt.com and enter a recipient's name, e-mail and a message. When the recipient recieves the message, a wiggling Heinz ketchup packet greets them, and then explodes to fill the computer screen with red ketchup. As the ketchup oozes off the screen, the user is able to read the personalised message (inside a Heinz label) and an invitation to send "splirts" to other friends. The campaign lasted only a few months, but was so popular that it has stayed live long after the campaign. To date splirts have been sent from or to nearly every wired country, have been featured on numerous cool sites of the day and continue to generate substantial traffic and of course "splirts"!
