In North America, not many new programs air on Saturday nights, with the focus more on movies, reruns and sports. This is largely due to the increasing status of Saturday prime time as a "death slot", which led most American broadcast networks to abandon first-run scripted fare on that night by the mid-2000s. In Canada, CBC Television has historically aired Saturday night NHL ice hockey nationally under the title "Hockey Night in Canada", dating back to the early days of radio. Other Canadian networks use the Saturday night slot to meet Canadian content quotas (a practice colloquially known as the "Canadian content"). The U.S.-based Fox network established a permanent sports block on Saturday night in 2012, carrying a range of sports including Pac-12 Conference Fox College Football, Major League Baseball on Fox, NASCAR on Fox and the Fox UFC on a periodic basis with reruns airing when sports events are not scheduled (this block displaced Fox's long-running reality series "Cops" from its time slot of over two decades); ABC carries Saturday Night Football during the fall, then switches to a mix of NBA on ABC, movies, news magazines and prime time reruns for the rest of the year.
