Raidió Teilifís Éireann  is Ireland's public service broadcaster, funded by a television licence fee and advertising. RTÉ operates two national television channels, RTÉ One and RTÉ Two. The other independent national television channels are TV3, 3e, UTV Ireland and TG4, the latter of which is a public service broadcaster for speakers of the Irish language. All these channels are available on Saorview, the national free-to-air digital terrestrial television service. Additional channels included in the service are RTÉ News Now, RTÉjr, and RTÉ One +1. Subscription-based television providers operating in Ireland include Virgin Media and Sky. Supported by the Irish Film Board, the Irish film industry grew significantly since the 1990s, with the promotion of indigenous films as well as the attraction of international productions like Braveheart and Saving Private Ryan. A large number of regional and local radio stations are available countrywide. A survey showed that a consistent 85% of adults listen to a mixture of national, regional and local stations on a daily basis. RTÉ Radio operates four national stations, Radio 1, 2fm, Lyric fm, and RnaG. It also operates four national DAB radio stations. There are two independent national stations: Today FM and Newstalk. Ireland has a traditionally competitive print media, which is divided into daily national newspapers and weekly regional newspapers, as well as national Sunday editions. The strength of the British press is a unique feature of the Irish print media scene, with the availability of a wide selection of British published newspapers and magazines. Eurostat reported that 82% of Irish households had Internet access in 2013 compared to the EU average of 79% but only 67% had broadband access.
