Network programming and scheduling[]
As of October 1, 2023, the CW provides 18 hours of regularly scheduled network programming each week, over the course of seven days. The network offers 15 hours of prime time programming to its owned-and-operated and affiliated stations, airing from 8:00 to 10:00 p.m. Eastern and Pacific Time on Monday through Saturday nights and 7:00 to 10:00 p.m. (Eastern and Pacific) on Sunday nights. 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 Hearst Media Production Group) airs on Saturday mornings from 8:00 to 11:00 a.m. in all time zones.
Similar to Fox, along with network forerunners the WB and UPN, the CW uses the "common prime" scheduling practice, avoiding the 10:00 p.m. (Eastern and Pacific) hour broadcast by the "Big Three" networks (NBC, CBS, and ABC). The network, unlike the Big Three, does not air any national newscasts, late-night programming, and, since 2021, daytime programming. It also did not run prime-time programming on Saturday nights and during the primetime access hour on Sundays until the 2021–22 and 2023–24 broadcast seasons respectively. 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), preempting network prime time programming to a specific time period (New York City affiliate WPIX, for instance, preempts CW prime time to the afternoon hours).
The Hearst-produced Saturday morning block, One Magnificent Morning (which is subject to scheduling variances similar to the weekday hour in some markets, such as in Atlanta and San Diego), is designed to be tape delayed and therefore recommended to air in the same time slot in all time zones. However, it is broadcast one hour earlier on affiliates of the CW Plus in the Central, Mountain and Alaska Time Zones. In Guam, CW Plus affiliate KTKB-LD in Hagåtña airs the CW lineup on a one-day tape delay from its initial broadcast because of the time difference between Guam and the continental United States as the island is on the west side of the International Date Line.
Supernatural (which initially aired on the WB) was the final CW series carried over from either of the network's respective predecessors that continued to be broadcast, airing its final episode in November 2020.
The CW formerly aired short segments during commercial breaks within certain episodes of its programs known as "Content Wraps" – a play on the network's name – to advertise one company's product during part or the entirety of a commercial break, a concept since classified under the term of native advertising. The entertainment magazine series CW Now was inspired in part by the success of the Content Wraps as it was intended to be a series with product placement; the program was canceled in 2008, after a single 23-episode season. For the 2006–07 season, the CW reached an agreement with American Eagle Outfitters to incorporate tie-ins with the company's aerie clothing line as part of the Content Wrap concept within the network's Tuesday night schedule, which included subjects in the commercials commenting on plot points in each of the shows. The agreement was cut down to regular advertising in February 2007, after a fan backlash by viewers of both shows and general criticism of the campaign.
