Starting with the 2017–18 broadcast season, the block's running time was reduced to three hours and began airing from 8:00am to 11:00am. The CW returned the two hours of reclaimed time to the affiliates. Stations The CW has 32 owned-and-operated stations, eight affiliated stations owned by Paramount Global, and current and pending affiliation agreements with 220 additional television stations encompassing 50 states, the District of Columbia and three U.S. possessions. Counting only conventional CW affiliates and over-the-air affiliates of The CW Plus, the network has an estimated combined national reach of 100% of all households in the United States (or 330,866,316 Americans with at least one television set); this makes The CW the largest U.S. broadcast network by population reach percentage. As of January 2023, three U.S. states (Delaware, New Hampshire, and New Jersey) and three U.S. territories (American Samoa, Puerto Rico and the United States Virgin Islands) do not have their own locally-licensed CW affiliates, largely because those areas are either located within the broadcast ranges of stations in nearby states or served by out-of-market stations via cable or satellite. Delaware is served by Philadelphia's WPSG and Salisbury, Maryland affiliate WMDT-DT2, while New Hampshire is served by four CW stations based in three neighboring states (including Boston affiliate WLVI). New Jersey is served by WPSG and New York City affiliate WPIX. As a newer broadcast network, The CW maintains affiliations with low-power stations (broadcasting either in analog or digital) in a few markets, such as Reno, Nevada (KRNS-CD) and Boise, Idaho (KYUU-LD). In some markets, including both of those mentioned, these stations also maintain digital simulcasts on a subchannel of a co-owned/co-managed full-power television station. The CW also maintains a sizeable number of subchannel-only affiliations, the majority of which are with stations in cities located outside of the 50 largest Nielsen-designated markets and receive the network's programming via The CW Plus; the largest subchannel-only CW affiliate by market size, as of May 31, 2017, is KFMB-TV DT2 in San Diego, California. The Sinclair Broadcast Group is the largest operator of CW stations by numerical total, owning or providing services to 25 CW-affiliated stations, nine subchannel-only affiliates and one cable-only affiliate, covering 17% of all U.S. television markets; Nexstar Media Group is the largest operator of CW stations in terms of overall market reach, owning or providing services to 28 CW stations (including its largest affiliates in New York and
