Today, more than fifty national free-to-air networks exist. Other than the non-commercial educational (NCE) PBS, which is composed of member stations, the largest terrestrial television networks are the traditional Big Three television networks (ABC, CBS and NBC). Many other large networks exist, however, notably Fox and The CW which air original programming for two hours each night instead of three like the original "Big Three" do, as well as syndication services like MyNetworkTV and Ion Television which feature reruns of recent popular shows with little to no original programming. Fox has just about the same household reach percentage as the Big Three, and is therefore often considered a peer to ABC, NBC, and CBS since it has also achieved equal or better ratings since the late 1990s; as of 2019, it also programs the equivalent amount of sports programming as the Big Three. Most media outlets now include Fox in what they refer to as the "Big Four" TV networks.
