In the United States, local news is provided on local commercial broadcasting channels (some of which are television network affiliates). They can either be standalone newscasts that run for at least a half-hour or short segments that air attached to national morning newscasts approximately 25 and 55 minutes past the hour. As not all stations are owned and operated by a television network, the graphics, branding, and studio designs of a station's newscasts often differ from the network they are affiliated with although in recent years, affiliates have made some form of on-air reference to their corresponding networks in the branding of their newscasts. In addition, the local news departments of stations also superimpose their on-screen digital clocks, thermometers, and (occasionally) local news tickers on graphics provided by networks during morning network newscasts. Some cable channels are dedicated to local news coverage. Examples of this include NY1 in New York and WJLA 24/7 News (formerly NewsChannel 8) in the Washington, D. C. market.
