An internal link is a type of hyperlink on a webpage to another page or resource, such as an image or document, on the same website or domain. Hyperlinks are considered either "external" or "internal" depending on their target or destination. Generally, a link to a page outside the same domain or website is considered external, whereas one that points at another section of the same webpage or to another page of the same website or domain is considered internal.
However, these definitions become clouded when the same organization operates multiple domains functioning as a single web experience, e.g. when a secure commerce website is used for purchasing things displayed on a non-secure website. In these cases, links that are "external" by the above definition can conceivably be classified as "internal" for some purposes. Ultimately, an internal link points to a web page or resource in the same root directory.
Similarly, seemingly "internal" links are in fact "external" for many purposes, for example in the case of linking among subdomains of a main domain, which are not operated by the same person(s). For example, a blogging platform, such as WordPress, Blogger or Tumblr host thousands of different blogs on subdomains, which are entirely unrelated and the authors of which are generally unknown to each other. In these contexts one might view a link as "internal" only if it linked within the same blog, not to other blogs within the same domain.
WBAY-TV, virtual channel 2 (UHF digital channel 23), is an ABC-affiliated television station located in Green Bay, Wisconsin, United States. The station is owned by Media General. The station's studios are located on South Jefferson Street in downtown Green Bay (across from the historic Brown County Courthouse), and its transmitter is located in Ledgeview (shared with the transmitters of Wisconsin Public Television station WPNE-TV and Wisconsin Public Radio station WPNE (89.3 FM)).
WBAY-TV first signed on the air on March 17, 1953 as the second television station in Wisconsin, after WTMJ-TV in Milwaukee. It was originally owned by the Norbertine Order of Priests, whose abbey is in nearby De Pere. The priests run St. Norbert College in De Pere, and already operated WBAY radio (1360 AM, now WTAQ) in Green Bay and WHBY radio in Appleton. Like WTMJ when that station started in 1947, as the only station in the market, WBAY originally carried programming from all four networks of the day – channel 2 was a primary CBS affiliate with secondary affiliations with NBC, ABC and DuMont.
