In March 2017, unconfirmed reports speculated that Sinclair was planning to shutter its sports unit, American Sports Network, and give its remaining sports rights to Campus Insiders. The Charleston Gazette-Mail, however, citing ASN employees, reported that the rumors of a complete shuttering were false, but that the division was planning to re-locate its headquarters, restructure its operations, and achieve "stronger, more diversified distribution." The original rumors were based upon reports of layoffs from ASN's current headquarters in West Palm Beach, connected to the planned re-location. On April 13, 2017, Sinclair officially announced that ASN would be re-launched later in the year as part of a joint venture with Campus Insiders owner Silver Chalice, and its online sports video service 120 Sports. The new operation will be operated as linear and digital offerings; the linear service would utilize the syndication and broadcast network built out for ASN, while the digital platform would stream full-time online and through Twitter. 120 Sports would provide original studio and long-form programming to the venture. On May 1, 2017, it was announced that the new joint venture would be known as Stadium. On June 1, 2017, it was reported that Stadium would officially launch around late-July 2017. The service officially launched on August 21, 2017. In 2019, with Sinclair's acquisitions of regional sports networksFSN, Marquee Sports Network and a minority stake in YES Network, Sinclair CEO Chris Ripley said of Stadium's role in the expanded sports offerings: "That will be our national play. I don’t see it competing head to head with FS1 or ESPN. It's not there yet with its maturity."
Distribution
The service is distributed mainly via streaming television services and associated apps. The American Sports Network linear service, which was distributed as a digital subchannel network, transitioned to Stadium on September 6, 2017. The network has also reached deals for traditional cable distribution. Stadium also offers a subscription service, "Stadium Plus", which offers access to premium events and on-demand content. In November 2017, Facebook acquired rights to 47 college basketball telecasts from Stadium, which stream exclusively on Facebook Watch and an associated Facebook page. In May 2018, Stadium partnered with Twitch to stream its content on the service, as well as an exclusive Twitch Stadium 2 channel that features additional commentary and analysis.
Programming
Stadium's college sports programming will include content from Conference USA, Mountain West Conference, the Patriot League, the Southern Conference, and the West Coast Conference. Stadium's studio lineup includes: The Territory - The Territory sets the editorial cycle for the day with a fast-paced, expansive look at the sports landscape, featuring news and storylines from coast-to-coast.

Each day, a different conference will be highlighted with exclusive interviews, Top 25 breakdowns, game picks and more. The Rally: Gametime in America - Gametime in America sets the live sports scene as viewers will navigate in real time through the landscape of sports in America. Ring of Honor Wrestling, the weekly professional wrestling television series produced by the Sinclair-affiliated promotion Ring of Honor, began airing on the network from January 2018. The series was previously syndicated to sibling broadcast network Comet. Stadium, as with other networks distributed by digital multicast networks, is required to preempt three hours of its weekly schedule for educational children's programming. With the exception of DragonflyTV, most of Stadium's educational shows are sports-related to minimize interruption; The Real Winning Edge, Sports Lab, Future Phenoms and Sports Stars of Tomorrow make up Stadium's educational lineup as of 2019.
