Talk to your neighbors about their television viewing habits and you will probably find that, although the range of programmes watched is pretty narrow, the methods for receiving them vary wildly from house to house. Some people get their favorite shows via gaming consoles, some by downloading them on a PC; some by playing them through a device such as Apple TV; some are satellite customers; while others doggedly stick to so-called "linear" viewing on the standard terrestrial channels, albeit received through a digital system.
