Who owns it?

Official Website:

Q: Isn't Dr Pepper/Seven Up owned by a major cola company?
A: No. While Coke and Pepsi are bottling partners that produce and deliver a substantial amount of our soft drink volume to retailers, neither owns DPSU. DPSU is a wholly owned division of London-based Cadbury Schweppes plc.
