Comfort & Via Naturals concept - a first sign of brand migration?

I spend two hours a day commuting to and from work and that's probably the reason why I do a lot of brand and innovation spotting as I travel. Yesterday I saw the new ads for the new Naturals concept by Unilever. This new concept has interestingly enough been launched as part of both the Comfort and Via brands. And it's the concept graphics rather than the umbrella brand graphics that hold the concept together. So, what is Naturals then? It is a concept focussed on the emotional and functional benefits of 'a more natural wash'. And, since it's being launched under both the Via and Comfort brands it may also be a first sign of a brand migration strategy. Will either Comfort or Via become the big detergent brand? Unilever are known to be clever about how to maximise the potential of their brands. And they have a good track record of extending brands to cover new territories. I'll certainly be following Via and Comfort more closely from now on. That'll be all today!
