largest overall audience ever tallied in U.S. television history. Stations Fox has 18 owned-and-operated stations, and current and pending affiliation agreements with 226 additional television stations encompassing 50 states, the District of Columbia and three U.S. possessions; through its Fox Television Stations subsidiary, Fox has the most owned-and-operated stations of the major American commercial broadcast networks. The network has a national reach of 95.77% of all households in the United States (or 299,268,292 Americans with at least one television set). Currently, New Hampshire, New Jersey and Delaware are the only U.S. states where Fox does not have a locally licensed affiliate (New Hampshire is served by Boston's WFXT, New Jersey is split between New York City O&O WNYW and Philadelphia O&O WTXF, while Delaware is served by WTXF and Salisbury, Maryland affiliate WBOC-DT2). Fox largely discontinued analog broadcasts on June 12, 2009, as part of the transition to digital television. As a newer broadcast network, Fox still has a few low-power affiliates, covering markets like Youngstown, Ohio (WYFX-LD). In some markets, including both of the ones mentioned, these stations also maintain simulcasts on a subchannel of a co-owned/managed full-power television station. Fox also maintains a sizeable number of subchannel-only affiliations in cities located outside the 50 largest Nielsen-designated markets that do not have enough full-power stations to support a standalone affiliation or have a low-power station as the only other option as an affiliate, though a couple have appeared in the top 50; the largest subchannel-only Fox affiliate by market size is WSYX-DT3 in Columbus, Ohio, #34 by Nielsen. Currently outside Fox's core O&O group, Nexstar Media Group is Fox's largest affiliate group in terms of overall market and numerical reach, with 42 stations (including some former Fox O&Os that were spun off in 2008 to Local TV, which Tribune Broadcasting later acquired in 2013, to finance former Fox parent News Corporation's purchase of The Wall Street Journal; Nexstar purchased Tribune in the fall of 2019); the Sinclair Broadcast Group is the second largest operator of Fox stations by numerical total, owning or providing services to 26 Fox-affiliated stations. Fox previously distributed its programming in markets that did not have enough stations to support an affiliate via Foxnet, a cable channel acting as an alternate national feed for small and certain mid-sized U.S. markets (generally those within the bottom 110 Nielsen media markets) that launched in 1991 and operated until
