Television channels specifically built to run on cable or satellite blur the line between TV station and TV network. That fact led some early cable channels to call themselves <a href="/wiki/Superstation" title="Superstation">superstations</a>. </p><p>Satellite and cable have created changes. <a href="/wiki/Local_programming" title="Local programming">Local programming</a> TV stations in an area can <a href="/wiki/Retransmission_consent" title="Retransmission consent">sign-up</a> or even <a href="/wiki/Must-carry" title="Must-carry">be required</a> to be carried on cable, but content providers like <a href="/wiki/TLC_(TV_channel)" class="mw-redirect" title="TLC (TV channel)">TLC</a> cannot. They are not licensed to run broadcast equipment like a station, and they do not regularly provide content to licensed broadcasters either. Furthermore, a distributor like <a href="/wiki/Turner_Network_Television" class="mw-redirect" title="Turner Network Television">TNT</a> may start producing its own programming, and shows presented exclusively on pay-TV by one distributor may be <a href="/wiki/Television_syndication" class="mw-redirect" title="Television syndication">syndicated</a> to terrestrial stations. The cost of creating a nationwide channel has been reduced and there has been a huge increase in the number of such channels, with most catering to a small group. </p><p>From the definitions above, use of the terms <i>network</i> or <i>station</i> in reference to nationwide cable or satellite channels is technically inaccurate. However, this is an arbitrary, inconsequential distinction, and varies from company to company. Indeed, the term <i><a href="/wiki/Cable_network" class="mw-redirect" title="Cable network">cable network</a></i> has entered into common usage in the United States in reference to such channels, even with the existence of <a href="/wiki/Satellite_television#Direct_broadcast_via_satellite" title="Satellite television">direct broadcast satellite</a>. There is even some geographical separation among <i>national</i> pay television channels in the U.S., be it programming (e.g., the <a href="/wiki/Bally_Sports" class="mw-redirect" title="Bally Sports">Bally Sports</a> group of regional sports channels, which share several programs), or simply regionalized advertising inserted by the local cable company. </p><p>Should a legal distinction be necessary between a (location) channel as defined above and a television channel in this sense, the terms <i>programming service</i> (e.g.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup>) or <i>programming undertaking</i> (for instance,<sup id="cite_ref-2" class="reference"><a
