Appy BBC

There's some mild interest on my slice of the Twittersphere this morning that Radio 4 has changed its Twitter logo. It's not clear whether or not legendary PR company Perfect Curve were involved. I can't remember the previous handle - nor determine whether it's part of a wider change. Which may or may not tell you something about the impact. But I was surprised by some of the imagery that goes with BBC Radio Twitter homepages. Is Radio 4 really a cosmic network ? Do Radio 3's current graphics - Yellow Submarine-meets-Game of Thrones - really reflect the station's sound ? Radio 5 Live seems to have opted for a dull shot of a studio that might or might not be used by some presenters - and 6Music has connotations of pill-taking.
