The channel launched on 13 March 2011, and featured reality programming, as well as an interactive live show and music content.

Leading up to the launch of U, there were 13 days' worth of promotional videos and programming information aired to advertise the new channel.

During its closedown period of 12-midnight to 12-noon, the channel looped a video of non-stop dancing with text reading U 'returns at midday'.

On 29 July 2013, TVNZ announced that U would cease broadcast on 31 August 2013, after two years since the channel launch.

Viewers were invited to participate via a Facebook application, where they could vote in polls, take part in discussions, and view the show via a live commercial and graphic free stream.
