Archangel Network

The Archangel Network was the main network on Earth from early 2007 onwards. It was a series of 15 artificial satellites in stationary orbit around the planet, and even all other networks ran on it.

It was designed by the Master in the guise of British Minster of Defence, Harold Saxon. The Master had an ulterior motive for putting the satellites in orbit, that is for the purporses of mind control, which was composed of a weak signal of four drumbeats, in which were coded a message telling any Humans to trust Saxon and vote for him in the upcoming 2008 election for Prime Minister.

In an alternative timeline, one which was erased a year after it diverged, the Network advanced to give Humanity a global consciousness, and was used to make all fear the Master and so be subservient to him. However, this telepathic field also caused the Master's demise, as when all the slaves on Earth revolted against the Master shouting cries and thoughts of "Doctor!" due to the stories told to slaves by Martha Jones, the Doctor (who had been aged 900 years by the Master's laser screwdriver) was rejuvenated, became a temporary sort of god. The timeline was then erased when the Master was distracted by Jack Harkness's destruction of the paradox machine in the Doctor's TARDIS. (DW: The Sound of Drums / Last of the Time Lords)
