One of just a few comments that goes against the grain:
“Richard Desmond’s company produces red-top tabloids, celeb mags and porn channels. They are no doubt aiming to move Channel 5 (which has never been exactly up-market) into a similarly down-market position. Look at some of the other logos.
“All of them would receive a slating on sites like this, but they work, and they draw in the intended audience (the kind of people who would probably consider most of the logos that receive good reviews on here as too arty-farty). The new Channel 5 logo is perfectly in keeping.”
You can see the full evolution of Channel 5’s idents in this archive from 1997 to 2010.
For a channel identity that really works, I’ve always loved Channel 4.
