More4 ('Channel 4 without the silly bits') began on 10th October 2005, and was available on Freeview from the outset. The channel was touted as being a more accessible competitor to BBC4, and included its own daily in-depth news programme.
This relatively highbrow approach clearly proved to be unsustainable for a commercial channel, as in January 2012, More4 was reformatted as a more lifestyle-orientated channel. At that point, the original graphical idents, as seen in the first image here, were replaced by a series of live action idents. These survived the 2018 rebrand, and were simply amended to feature the new More4 logo.
