The NBC Television Network, the CBS Television Network, the American Broadcasting Company, the Public Broadcasting Service and the Fox Broadcasting Company are popular channels that can be received using an antenna. The CW, Omni Television, ION, CTV and Univision are also available with an antenna, as of 2015.
Although an antenna offers access to popular channels, it has a few limitations not encountered with cable, satellite or Internet connectivity. A network uses local affiliates to provide its antenna-receivable programming, resulting in local decisions on what to air. The network schedule may not be full-time or may be superseded by locally produced shows. Also, a particular location's proximity to the broadcast towers affects station reception in that area.
Network corporations typically limit over-the-air content to core businesses. Fox Broadcasting Company airs its full lineup, but nothing from the Fox News Network. The American Broadcast Company provides no shows from other Disney-owned networks ABC Family or the Disney Channel. The CBS Corporation offers its CBS Television Network and CW shows, but not CBS Sports Network or Smithsonian shows. NBC Universal broadcasts some sports on NBC Television, but reserves most for NBCSN network, limited to cable and satellite viewers.
Serving a Spanish-speaking audience, Univision and Telemundo are also distributed to broadcast stations.
