Digital terrestrial television (DTT) is the UK's most widely used TV platform, available to virtually all households. At the heart of this is Freeview - the free-to-air service watched by three-quarters of UK homes. Freeview offers more than 70 digital TV channels, radio stations and interactive services via an aerial, with the added benefit of simple digital recording and free high-definition channels from the UK's top broadcasters.

The popularity of DTT puts it on course to continue growing and evolving in the coming years. Its scale and enduring appeal also help underpin a range of benefits including:

*    Universal availability of public service TV
*    Greater consumer choice
*    Competition between TV platforms
*    Investment in UK-made programmes

The new offer gives viewers easy access to both linear and on-demand content, including a range of popular catch-up players, free from subscription.
