Overview
Sinclair Broadcast Group is the operating name of Sinclair, Inc., a publicly traded American telecommunications and television broadcasting company. Its roots extend to the Commercial Radio Institute, a Baltimore broadcasting trade school established in the late 1950s by electrical engineer Julian Sinclair Smith and his wife, Carolyn B. Smith. The organization entered radio broadcasting with WFMM-FM, now WPOC, in 1960 and later built WBFF in Baltimore, which began broadcasting in 1971. The company adopted the Sinclair Broadcast Group name in 1985 as Smith's sons became increasingly involved in management and expansion. Sinclair grew primarily by acquiring local television stations and station groups. In the early 1990s it developed a significant role in local marketing agreements, under which one company could provide programming, sales, technical or administrative services for a station licensed to another owner. These arrangements allowed Sinclair to expand its operating footprint while navigating Federal Communications Commission ownership limits. The structure also generated regulatory criticism, particularly over the relationship between Sinclair and Glencairn, later associated with Cunningham Broadcasting. In 2001, the FCC fined Sinclair for exercising prohibited control over Glencairn. The company became publicly listed on NASDAQ in 1995, raising $105 million through an initial offering while the Smith family retained control. During the 1990s and 2000s, Sinclair expanded its network affiliations and station portfolio through acquisitions involving Fox, UPN, The WB, ABC, CBS, NBC and The CW. A major acquisition cycle began in 2011, including Four Points Media Group and the television stations of Freedom Communications. Further purchases included stations from Newport Television, Cox Media Group, Barrington Broadcasting, Fisher Communications, Titan TV Broadcast Group and Allbritton Communications. These transactions made Sinclair one of the largest American television station operators. Sinclair's business has broadened beyond traditional local stations. It owns or operates digital multicast networks including Comet, Charge!, The Nest and Roar, and owns the sports-focused Tennis Channel. It also acquired the professional wrestling promotion Ring of Honor in 2011 and has operated other media and broadcast-support businesses. Sinclair's station portfolio includes affiliates of Fox, NBC, CBS, ABC, MyNetworkTV and The CW. Its stations provide local news, syndicated programming, network programming, advertising inventory and digital distribution. The company has attracted extensive political and regulatory scrutiny. Critics and media researchers have characterized Sinclair's corporate news initiatives as politically conservative, citing centrally produced commentaries, must-run segments and election-related programming. A 2018 video showing anchors at numerous Sinclair stations reading substantially similar language about media trust became a major national controversy. Sinclair has defended its editorial initiatives as efforts to provide local audiences with reporting and commentary that are not adequately supplied by other media organizations. Sinclair remains a major U.S. broadcast operator, although its financial position, acquisition strategy and regulatory relationships have changed over time. It reached Fortune 500 status in 2021 after reporting 2020 revenue of approximately $5.9 billion. Its present business combines local television station operations with national networks, sports programming, digital distribution, advertising and broadcast infrastructure. The company is best understood as a station-centered media group whose scale is built on ownership, operation and service agreements across more than 100 U.S. television markets.
History
Sinclair's origins lie in Baltimore's Commercial Radio Institute, founded in the late 1950s by Julian Sinclair Smith and Carolyn B. Smith. The organization initially combined broadcasting education with station development. The FCC granted a construction permit for an FM station in 1959, and WFMM-FM began broadcasting in February 1960. A subsequent UHF television project produced WBFF in Baltimore, which launched on April 11, 1971. The early television business operated under Chesapeake Television Corporation. It established WPTT in Pittsburgh in 1978 and WTTE in Columbus in 1984. These stations initially operated as independents, but WBFF and WTTE became charter Fox affiliates in 1986. Sinclair's early local-news experiments included WPTT News, an unusually ambitious service for an independent station at the time. Local news became a much larger part of the company's strategy after the mid-1990s, as Sinclair acquired network-affiliated stations and built shared production and management systems. The company adopted the Sinclair Broadcast Group name in 1985. David D. Smith and his brothers became more active in management and, in 1990, acquired their parents' remaining stock. Sinclair subsequently pursued an aggressive acquisition program. In 1991, it pioneered a major use of local marketing agreements by selling WPTT to a related outside licensee while retaining operational responsibilities and acquiring WPGH-TV. The model helped Sinclair expand under ownership restrictions but also led to persistent criticism that affiliated licensees were not genuinely independent. Sinclair went public on NASDAQ in 1995. Its network strategy changed repeatedly as it signed agreements with UPN, The WB, Fox and later The CW. Acquisitions in the 1990s included Superior Communications, Sullivan Broadcasting and Max Media Properties. The company also disposed of selected stations, including KSMO-TV and KOVR-TV, as it adjusted its portfolio. In 2001, the FCC fined Sinclair for improper control of Glencairn, a regulatory episode that became an important reference point in debates over Sinclair's use of shared-service structures. After a period of financial pressure, including a 2009 disclosure concerning refinancing risk and debt, Sinclair entered a new expansion phase. It purchased Ring of Honor in 2011, Four Points Media Group and Freedom Communications' stations. In 2012 and 2013 it added stations from Newport Television, Cox Media Group, Barrington Broadcasting, Fisher Communications, Titan TV Broadcast Group and Allbritton Communications. The Allbritton deal, which included WJLA-TV, required extensive FCC review and station divestitures before closing in 2014. Sinclair also purchased Dielectric Communications, a broadcast-antenna supplier, in 2013. Sinclair continued developing national programming assets and multicast services. Its portfolio came to include Comet, Charge!, The Nest and Roar, while Tennis Channel provided a national sports platform. Ring of Honor Wrestling supplied programming to Sinclair stations and other outlets. These businesses complemented the company's core local-station model by creating additional inventory, distribution opportunities and national advertising products. The group became increasingly prominent in national media-policy debates. Its stations were frequently associated with centrally distributed commentaries, must-run segments and election-period specials that critics viewed as promoting conservative political positions. In 2018, a widely circulated video showed anchors at many Sinclair stations delivering similar warnings about media bias. The episode intensified scrutiny of consolidation, editorial independence and the effects of station ownership on local journalism. Sinclair's proposed 2017 acquisition of Tribune Media represented an attempt to create an even larger U.S. television group. The transaction faced regulatory resistance, especially concerning proposed divestitures and Sinclair's relationships with stations operated through affiliated companies. The deal was terminated in 2018. Sinclair nevertheless remained one of the country's largest television station operators, with stations in more than 100 markets and affiliates of the major broadcast networks. In 2021, it entered the Fortune 500 following strong reported revenue in 2020. Its continuing business combines local broadcast stations, news production, national sports and entertainment networks, digital multicast channels, advertising and broadcast-related services.
