Until a few years ago, East Germans were discouraged from watching Western television and aerials turned to the West were ripped down by Party vigilantes. But it was a difficult rule to enforce. It seemed more sensible to improve their own programmes and it worked. Today in the two Berlins you can switch from East to West and find a comparable selection of programmes. Of course attitudes are different, and even if each side claims to be uninterested in its potential audience across the border, there is, nonetheless, a continual television dialogue across the wall.
Charles Wheeler, who was BBC correspondent in Berlin at the end of the war, reports on the two societies and their television.

Twiggy painted by Peter Blake
' You don't think I've gone down 'ill then? ' ' You're prettier than ever; the trouble with watercolour is that you can easily lose it, and I think I've just lost it.'
Concentration broken by TV lights, BLAKE graciously admitted defeat and took the picture away to finish it from photographs. During the session they talk about the 60s and one of the pop icons of that era, the Sgt Pepper album cover. Blake explains how the myth surrounding the cover developed, and why they got it wrong.
