In 1958 I was hired as a researcher by Granada where, among other things, I wrote the weather forecast. I mentioned anti-cyclones and was told: 'We don't use words like that here, it's either wet or dry.' I thought that was marvellous - it didn't matter that you could translate a line or two of Homer; what mattered was that you could communicate. I quickly realised I wanted to use the medium to explain the world to people. After only 18 months at Granada I was producing What the Papers Say.
Making programmes is one of my two great satisfactions. The other is creating the space in which others can fulfil their potential. I am hugely proud of The World at War, but when I say I 'made' it, the truth is it took 50 people three years to make.
The most exciting and difficult thing I ever had to do was get Channel 4 off the ground. We started with an almost blank piece of paper, and we had an absolute whale of a time doing things no-one had done before. Setting it up was far more exciting and rewarding than just keeping it on an even keel, so I put in to become director general of the BBC. When I didn't get that, I went to the Royal Opera House - the biggest gamble I ever took.
I've never regretted that move, but it came at a time of appalling under-funding of the arts. Perhaps that's easier than having lavish resources. Who knows? No-one in the creative industries has ever had lavish resources.
