24 Carat
From Tardis Wiki, the free Doctor Who reference
CARAT 24 was an organisation run by Melanie Bush. It began as a humble Carrot Juice Business but expanded into a technology, health, and lifestyle empire stretching right across the galaxy, so much that it had a show where people would present their prototype products to win a Carat 24 partnership.
