They said Virgin on them in big letters so Virgin being a very forwards thinking company realized that this was very good for marketing and promotion. At the same time though they took this one step further by demonstrating they were in on the joke and having ‘stolen from Virgin’ written on the bottom. Again this actually encouraged people to steel the pots and kept it fun and risky at the same time. More than that though this kind of wit is the sort of thing that catches on, and that’s what made these pots become desirable and added to the ‘cool’ image that Virgin has always tried to maintain. This then also helped to generate buzz and get people talking about the pots and even lead to more people wanting them. This way the promotional products on their own created the viral effect spoken about above, while also making logical sense within the context of the business.
