Virgin brands

Brand extension refers to the use of a successful brand name to launch a new or modified product or service in a same broad market. A successful brand helps a company enter new product categories more easily.
But how far can you go with putting your brand on products and services?
Virgin is well known (mostly due to Richard Branson) and its recognizable by the red color and the Virgin logo, but when you see all the logos together of all the Virgin products and services, I think it’s time to work on a damn good styleguide.
