As part of Radio 4's Year of Culture initiative, the BBC Arts Editor Will Gompertz meets the cultural entrepreneurs who are shaping our lives and defining the very spirit of our age.

These are not Turner Prize winners or the recipients of grants from the Arts Council or the Lottery Fund. These are the people behind the scenes, pulling the strings and plotting a path of consumer-driven success. They are the designers of the latest 'must have' piece of technology or clothing, the brains behind an artist's development, and the tastemakers that know what will work at the box office and what will sell on the high street. Their impact goes beyond mere commerce, it shapes contemporary culture. They are the Zeitgeisters and it's about time we met them.

Programme 4. In the final programme of the series, Will meets Daphne Koller & Andrew Ng, co-founders of Coursera, the company that is revolutionising education much in the same way that Amazon and iTunes turned publishing and music on their heads. Daphne and Andrew have together created a platform which allows anyone from anywhere in the world (who has internet access) to attend lectures and classes given by the best teachers in the world - for free. Universities as we know them may soon be a thing of the past.
