John Davies surveys the broadcasting schedules (all times pm unless stated).

Pick of the week

Channel 4's new Sunday-night series The Day the World Took Off (8.00) is an interesting attempt to do something different with history: using the first railway journey from Liverpool to Manchester in 1830 as a framework, it sets out to explain the industrial revolution's origins in northwest England. An academic team featuring two from Cambridge University (Simon Schaffer, Alan MacFarlane), Warwick University's Maxine Berg, Christopher Cullen of the School of Oriental and African Studies and Joel Mokyr of Northwestern University (Illinois) offer theories, including the notion that tea was important to the health of urban populations. Later programmes will go further into the past to examine the roots of technological progress.
