I used to watch Read All About It when Melvyn Bragg fronted it. That was 1977 and books, often quite serious ones, were suddenly being marketed in the way that albums had been and their authors were being encouraged to style themselves like rock stars. It must have been quite rigorous. I was just listening to an old exchange between Martin Amis and John Pilger on the programme. It achieved Newsnight-levels of testiness.
I haven't watched a book programme in years. I've never read more books, never bought more books and probably never read more reviews of books, but I don't have the patience to watch a bunch of authors being interviewed or some critics comparing notes. What information or opinion value such programmes may once have had I can now obtain somewhere else.
(In fact I no longer watch the kind of TV that features people discussing things at all. I've realised in the last couple of weeks how little TV I watch when I've been introduced to a couple of people who were, to judge from other people's reactions, quite famous. It's not entirely true to say I had no idea who they were but an idea was all I had. I'd never seen them.)
We'll probably get by without a books programme on the TV. We managed without Barry Norman's film programme. It's apparently still on but presented by somebody else.
