In order for digital television to flourish broadcasters needed both public supported channels to adopt the platform and also commercial ones. It is necessary to have adverts on television as this provides a vital income stream to television companies. Freeview offers more channels on it’s digital transmission signals and so more channels are able to be viewed through your set-top-box. It is inevitable that Freeview could not rely solely upon public broadcasters and so transmission slots are offered to commercial stations. With the cost of television technology going down it is possible to transmit a TV channel for much less than previously possible making it much more accessible. Other digital television technologies also support this including digital terrestrial Freeview television.
