GBA Tennis Interactive Lesson - Part 1

Found this great interactive TV ivideo series using YouTube annotations technologies made by Canadians, which claims to be the first interactive tennis lesson on YouTube. Tried it out and it's kind of weird and amazing and fun, if you're into tennis. Pretty well done when you consider that the creators (tennis pros) had to think through all the interactive options to make this work. I really give them credit for doing this and not making it cheezy.  -- Tracy Swedlow, [itvt]
