Virgin ... can it do no wrong?

There are brand extensions and then are Virgin extensions, who have now applied the brand to a range of water purifiers... sure the name fits but can the Virgin brand be applied to everything from telecommunications, travel (even space), fitness, entertainment and still survive?
Most companies by now would have diversified into a family of brand names each according to a set category but Virgin, and I have sung their praises before, have managed to successfully apply the same brand across a wide variety of products.
While water purifiers may seem a bit random at best, I truly believe that Virgin deserve to be included in the list of best of global brands due to their sheer ability of adapting their brand from just a name to a lifestyle choice and maintaining its image through what may come.
