When we browse the internet, we choose which websites we want to view and when we want to view them. However, TV viewing has always been limited to a schedule of programmes on specific days and at specific times.
TV aerials have come a long way since the times of waving the bunny-eared aerial on top of the TV around to get a signal for three channels.
All flat screen TVs now come with built-in Freeview that can be accessed via a Freeview aerial, so you have the choice of up to 60 British TV channels without having to sign up for a subscription package such as Sky.
