ii) broadcast anniversary
6 July 2009: broadcast of the first episode of Torchwood: Children of Earth, with the children stopping in place and chanting, and sinister goings-on at the top of the government; at the end Jack gets blown up in the Hub, and the wains chant "We are coming back". Thrilling stuff.
