Pre-launch promo for the new channel broadcast on 4th July 2012. The final caption has the new channel numbers for the different platforms.

In the weeks leading up to the launch, the promo above played out with this end caption.

Animated holding caption broadcast on Freeview from mid-morning on 4th July 2012.

At midday, there was a four-minute long engineering test, previewing the channel's presentation. It was accompanied by a stereo sound test signalled by the two white squares.

At 2pm, following the pre-launch trailer, another example of the ECP test animation played out but with a different font.

Yet more testing. Strange that this is being done 'on-air'.
