However, BBC Four had much more of an arts bias to begin with, and watching back the continuity announcements I recorded from the opening night reminded me how impenetrable the channel felt at the very beginning; it took a year or so for it to lighten up a bit. There's no way they'd have shown anything as frivolous as Top of the Pops back then!
Indeed, I remember when they bought Curb Your Enthusiasm, Roly Keating specifically said he wanted to get more comedy on the channel because he'd felt it was a bit forbidding. Certainly for the first year BBC4 was far more niche and serious than the quirky, entertaining channel we have now, there were loads more arts programmes on it, but I like how it's been made more appealing without losing any of its authority or intelligence. I think Sky Arts is quite similar to the early BBC4 line-up.
I remember the Radio Times (who, amusingly, forgot to change the channel heading so billed the first week's BBC4 output as BBC Knowledge) pointing out that George Alagian presented BBC4 News without a tie, making his the first BBC newsreader to do so. I assume that the change from BBC4 News to World News Today was to cut costs, simply simulcasting BBC World, though I think it was always simulcast on BBC World.
The original BBC Knowledge was a hopeless idea, like the original BBC Choice they were simply stumbling around for ideas of what might work on difital telly, but this was just like watching the Open University all day.
