Grayson Perry: 'If I have a show and I get an audience of about 100,000 people, I’m doing really well as an artist. But if you make a television programme and you have 100,000 people, you’re out of a job. As an artist, I’m in the business of expressing myself and communicating things I’m interested in. I enjoy participating in the national conversation. But I can understand how easy it is to get sucked into making things to feed the beast that you’ve created, so I shall be wary of that and I shall only make programmes that I want to make.'
