Specialty channel
A specialty channel can be a commercial broadcasting or non-commercial television channel which consists of television programming focused on a single genre, subject or targeted television market at a specific demographic. History. The number of specialty channels has greatly increased during the 1990s and 2000s while the previously common model of countries having just a few (national) TV stations addressing all interest groups and demographics became increasingly outmoded, as it already had been for some time in several countries. About 65% of today's satellite channels are specialty channels. Types of specialty services may include, but by  no means are limited to: (These categories are provided for convenience and do not necessarily represent industry-accepted or otherwise legally-binding names or categories for these types of services.) Some specialty channels may not be free-to-air or may not be available through conventional broadcast or terrestrial television. In the United States, such networks are colloquially referred to as cable channels or cable networks (regardless of distribution method), with the most widely distributed referred to as "basic cable" networks. In the U.S., specialty services also operate as broadcast television networks designed to be carried on digital subchannels of  terrestrial stations (which proliferated following the transition from analog broadcasting), with the largest usually focusing on library programming catering to specific genres or demographics. Canadian specialty channels. The term "specialty channel" has been used most frequently in Canada, having been used as a marketing term by the cable industry for various simultaneous launches of new channels throughout the 1990s. The Canadian Radio-television and Telecommunications Commission (CRTC) term for such a channel is specialty "service" (or even more explicitly "specialty television programming undertaking"), referring to virtually any non-premium television service which is not carried over the airwaves or otherwise  deemed exempt by the CRTC. They are primarily carried, therefore, on cable television and satellite television. The CRTC previously enforced strict regulations on the types of programming that may be carried by specialty services, employing minimums and restrictions across specific genres on a per-licence basis, and a category system granting exclusive rights to specific categories of channels. These restrictions were imposed to discourage networks from deviating from the programming format which they were licensed to broadcast. Under a deregulation scheme, the CRTC has since replaced these with streamlined, standard terms for most specialty channels (discretionary services), whose only major  restrictions are on the broadcast of live sports programming. Contrarily, a service licensed as a mainstream sports network is restricted in their carriage of non-sport programming.
