February 6, and Tom Martin as the Head of Business Affairs and general counsel on February 9. Programming Network programming and scheduling The CW airs its prime time programming for only two hours every night, compared to the three hours on Monday through Saturdays and four hours on Sunday nights programmed by the three longest-established networks, ABC, CBS, and NBC. This "common prime" scheduling (which was originated by Fox when it launched its primetime schedule in April 1987, and later adopted by CW predecessors The WB and UPN when they launched in January 1995) allows the option for affiliates to air either a local newscast, syndicated programming or both during the 10:00–11:00 p.m. (Eastern and Pacific Time) time period. As with The WB and UPN, The CW formerly did not run network programming on Saturday nights – even though it maintains a syndicated children's program block on Saturday mornings – allowing affiliates to run syndicated programs, sports, movies or network programs that were preempted from earlier in the week because of special programming carried by the station, in the 8:00–10:00 p.m. (Eastern and Pacific) time period (MyNetworkTV also does not carry any weekend prime time programming, having turned network time on Saturday evenings over to its affiliates in March 2007). The CW, unlike the "Big Four" broadcast networks, does not air any national newscasts or late-night programming, and did not program any network-supplied sports broadcasts until 2023. Because of these factors, The CW's affiliates handle the responsibility of programming non-network time periods, with the majority of its stations filling those slots mainly with syndicated programming. However, some of the network's affiliates broadcast their own local news and/or sports programs (either produced by the station itself or through outsourcing agreements with an affiliate of another network). The CW provides 17 hours of regularly scheduled network programming each week, over the course of seven days. The network provides fourteen hours of prime time programming to its owned-and-operated and affiliated stations nightly from 8:00 to 10:00 p.m. Eastern and Pacific Time (nearly as much programming as Fox which airs 15 hours of primetime programming). Outside of prime time, a three-hour educational programming block called "One Magnificent Morning" (which airs as part of the CW schedule through a time-lease agreement with Litton Entertainment) airs on Saturday mornings from 8:00 a.m. to 11:00 a.m. in all time zones. The Litton-produced Saturday morning block (the latter
