Are we overstating the case of the ZooZoo? Will viewers really remember Vodaphone's smorgasbord of different products and services? Or will they just remember the high jinks of these strange little fat-bellied egg-heads?

Perhaps it doesn't matter whether the specific services are remembered one way or another. Vodafone recognises a winner when they have one, and they've unleashed a full-on ZooZoo campaign.

There are ZooZoo-themed computer wallpapers, emoticons, e-cards, ring-tones, videos, a Twitter stream, etc -- all of this and more stemming from the original Rs 30 million advertisement campaign.

The ZooZoo dominates dinner table discussion, water cooler conversations and social networking web sites. The videos have been viewed over 3 million times in the past three weeks alone.

Visible Measures, a site that specialises in measuring the consumption and distribution of online video, says that the ZooZoo spots have been the web's most watched viral video two weeks running.

This is exemplary viral marketing in action.
