Last week, as television brought the riots in Britain into the living room, images from a visit to another town more than 20 years ago came hurtling back. It was early 1990 in Belfast, Northern Ireland. Apart from its notorious religious divide, what I remember most graphically about that city was a forest of dish antennae in a housing estate in a very poor neighbourhood. Satellite television had not yet arrived in India, and colour TV was still a status symbol.
