This isn't TPG's first foray into TV. Once upon a time TPG launched Boomerang TV ( http://en.wikipedia.org/wiki/TPG_Telecom#TPG_Boomerang_TV ) which was spectacular mess.
Boomerang TV ended with (as one insider put it) "a death of a thousand cuts", as a vicious circle of insufficient bandwidth, poor quality content, and low take-up contrived to push TPG to pull the plug on the venture.
Whirlpool forums ( http://forums.whirlpool.net.au/archive/619086 ) refer to another TPG IPTV push in 2006.
This is another attempt, in a long line of attempts, to get a viable TV service on TPG. Apparently David Teoh is a frustrated Rupert Murdoch ;-)
