ARD, one of Germany's public broadcasters, is actually an umbrella organisation made up of the different regional public broadcasters. This effectively renders ARD a case of where the regional stations own the network. One of ARD's channels, Das Erste, has exactly the same output across the country but each of the regional broadcasters contributes content to it. Meanwhile, each ARD-member broadcaster uses channel 3 to show its own output and lineup in the viewing areas they serve (although a common time exists for regional news bulletins at 19.30 and a simulcast of the national newscast "Tagesschau" at 20.00 Central European time). Within some regional broadcasters, further variations exist for the regional news bulletins. Viewers across Germany are able to view the different regional variations of channel 3 through free-to-air satellite, pay-TV subscription, or through the ARD media library available on ARD's website and mobile app.
