Sinclair, Inc. (Nasdaq: SBGI), formerly Sinclair Broadcast Group, is a diversified media company and one of the largest U.S. local television broadcasters. The company operates 177-185+ TV stations across roughly 79-86 markets affiliated with all major broadcast networks (Fox, NBC, CBS, ABC, MyNetworkTV, The CW), owns Tennis Channel, holds a stake in YES Network, and runs digital multicast networks Comet, Charge!, Roar, and The Nest. Sinclair Ventures houses the company's non-broadcast operations, including ad/martech units (AMP, Drive Auto, Free State, Digital Remedy/Compulse) and broadcast technology subsidiaries (Dielectric, ONE Media Technologies, Bitpath, CAST.ERA, Broadspan Wireless). In 2019 Sinclair acquired the Fox Sports regional sports networks for ~$9.6 billion through a Diamond Sports Group joint venture; Diamond was rebranded Bally Sports in 2021, filed Chapter 11 in March 2023, exited bankruptcy in January 2025 as Main Street Sports Group, rebranded again as FanDuel Sports Network, and is winding down operations in mid-2026. Sinclair runs no developer program and publishes no API documentation, but its corporate site at sbgi.net serves a live, public, unauthenticated WordPress REST API whose first-party sbg/v1 namespace publishes the company's full television station footprint — 197 primary stations and 365 digital subchannels across 87 Nielsen DMAs, with network affiliation, market rank and O&O/JSA/LMA/MSA ownership status attached to every call sign — alongside 1,753 press releases and the regional sports network territories.
