Bill Gates: How a Geek Changed the World

BBC Two, 7pm (Scotland: tomorrow 6pm)

As Bill Gates leaves the day-to-day running of Microsoft to focus on his $60 billion philanthropic foundation, The Money Programme talks to the geek who made good on his promise to put a computer in every home and in every office. (Mind you, he’s not quitting the day job entirely. “I get to make suggestions,” he says.)

The interview, which took two years to negotiate, examines the three facets of his career — as super-geek, super-competitor and latter-day saint. Money, he says, doesn’t matter to him. It merely “allows me to focus on the things I love doing”. And does he still get as angry as ever? According to a fellow geek: “The ratio of shouting to non-shouting has decreased.”

Gardeners’ World

BBC Two, 8pm

There are never preview DVDs available for Gardeners’ World, often because of the weather (they often don’t even know what they’re going to be filming in advance). This, then, is a rough guide to what might happen tonight. The proposed theme is tropical: Joe Swift is due to potter around the jungle garden among the bamboos and the tree ferns, while Carol Klein is supposed to be staking and pruning the hot end of the herbaceous border. And to get the most out of global warming, they will also see if houseplants can survive outside in the garden at Berryfields. Assuming, of course, that Warwickshire doesn’t get hit by a cyclone in the interim.

Deadliest Catch

Channel 4, 8pm

Halfway through the new series and — guess what? — the fishermen are still pulling crab pots out of the Bering Sea. But viewers who like variety are in for a treat tonight. One of the fishing boats goes in search of cod rather than crab.

It’s exactly the same process, mind, but cod look entirely different. So that’s quite exciting. Also, the crab being fished by the rest of the fleet are Opelio rather than King crab, and they are smaller. So watching the crew recalibrate the crab pots is pretty exciting, too. It won’t be long now before we can all enjoy a 16-part series about life in an Alaskan fish-processing plant.

Alexei Sayle’s Liverpool

BBC Two, 9pm

In the last of the series, Alexei Sayle continues to scratch away at the identity of Scousers — their religion, accent, creativity and all the rest. “If you wanted to be an entertainer,” he reckons, “there was no better place to be born. Everybody in Liverpool is a performer.” As a teenager, he always felt like an outsider — which may have had something to do with being an atheist, a communist and a Jew who didn’t like football. Making the series has changed his attitudes. “Things that I thought weren’t important to me — a sense of community, of friendliness on the streets, of being among my own people — actually are.”
