Paltalk is a web site that offers instant messaging, group video calls and chat rooms – all for free.

How do I know this? Certainly not because I was searching for a solution to my instant messaging and group video needs. I know because I received this video via email:

Notice the video doesn’t mention Paltalk. But when you decide to forward the video to a friend, you find out about Paltalk.

The video was created by a “buzz and communication” company called Vanksen/Culture Buzz. They offer a 100,000 view minimum guarantee on their videos, and they say their campaigns are 269-times more efficient than video banners.

So has it worked? I would argue it has (since I’m writing about it). But I’m more interested in the advertising agency. I poked around on their site for a little bit, and came across this great presentation on marketing 2.0.
