My5 initially saw beginnings as 'Channel 5 + 24' - a service designed to show the Channel 5 schedule a day later, but airing with very limited hours on certain platforms. In 2016 the service was completely relaunched with a separate brand and a much improved schedule in an attempt to launch a Channel 5 version of the 4Seven channel. It followed an earlier rebrand of Channel 5's ondemand platform under the same name, leading to a repeat of the BBCi situation from the early 2000s where it became necessary to distinguish in promotions between 'My5 Online' or 'My5 on TV'.
On February 13th 2018, possibly to get away from the ambiguous problem of referring to 'My5' for both their ondemand platform and a standalone channel, the channel was rebranded again as 5Select, albeit following a very similar graphic style to the previous My5. This followed an earlier planned but aborted launch as 5Prime in the January.
