I've heard that kinesiology taping is merely a term to avoid trademark or copyright issues with the Kinesio company. Kinesio Tape is still the leader in the US and has been available in the UK (and many other countries) for quite some time. KT Tape appears to be an imitation based on the fact that they've adopted a common nickname for Kinesio Tex Tape as their label.
The links posted previously -- Kinesio Tape and Kinesio Taping, Kinesio UK, and Kinesio Taping - Global are still your best bet.
