Already the basic pay of a headline BBC1 star such as Harry Enfield or Jennifer Saunders exceeds pounds 1m a year. These are the people who have programmes built around them, the stars whom ITV, Channel 4 and now Sky - which this week signed David Baddiel for pounds 5.5m for a new sitcom - fight over. It is the struggle between increasing numbers of channels to secure the headline names that is turning a generation of comics into millionaires.
"The biggest stars of comedy are very valuable to television stations," says Paul Jackson, the head of BBC entertainment, and the man who has to deal with stars' pay claims. "Not only because of ratings, but because there are a few stars who stations like to see themselves defined by. "For the BBC, they are an important part of the licence fee proposal. When people are asked why the BBC is good value they usually name comedy and then drama before they get around to mentioning Panorama. We may be valued for news and current affairs, but we are loved for our entertainment and drama."
For commercial television, young and usually male comics are even more important. Television audiences tend to be more female than male and older than the national average. But comedians bring in the highly valued, young male audience to whom advertisers want to sell cars and beer.
The pounds 20m demanded by Skinner's agent and production company, Avalon, included the cost of making the programme for five years. Skinner's share was likely to be no more than pounds 1.5m a year, the norm for top-rated comedy stars. David Baddiel's pounds 5.5m contract with Sky is also a deal for writing, starring in and making his sitcom.
Part of a comic's wealth in the Nineties comes from the fact that he is multi-talented and either owns or has a share in a production company - for example, Rowan Atkinson owns a share in Tiger Aspect. Not only are they more than just performers, often they take a fee as a producer and a writer.
Yet the money demanded by Skinner's agents is less than half of what he can expect to earn in the multi-media world of 1999. "Television is the shop window for the rest of their career," says Andrew Zein, commercial director of Tiger Aspect Television. "It is easier to do chat shows and then do something else than it is to go away on location and shoot a drama for six months. Once your six half-hour chat shows are out of the way, you can do your stage shows, advertising voice-overs, videos and novels."
This is why on any list of millionaire comedians you will find comics such as Roy Chubby Brown and Bernard Manning. They may be too offensive for television, but they have a lucrative parallel career on video or in clubs they own.
And, just like rock'n'roll bands, much of the money comes from exploiting yourself as a brand: "The Bottom and the Fast Show tours made more money for their stars from T-shirt sales than their television contracts," says Mr Jackson. "It's not that comedians are now better capitalists. It's just that the opportunities outside TV can dwarf what they earn on screen."
