Bally Sports started on March 31, 2021, when a group of regional sports networks formerly known as Fox Sports Networks adopted the Bally Sports name. The change was a rebrand, not the creation of an entirely new set of channels: the networks continued their regional coverage under new branding and ownership.
If you’re asking, “when did bally sports start,” the short answer is March 31, 2021. The longer story begins with the sale of the Fox regional networks, continues with a naming-rights agreement involving casino company Bally’s Corporation, and includes a later change to the networks’ name.
The Bally Sports launch date
Bally Sports launched on March 31, 2021. On that date, the regional networks that had been branded as Fox Sports Networks began using Bally Sports names, such as Bally Sports Arizona and Bally Sports Detroit. The specific channel names reflected the regions they served.
The launch followed an announcement in November 2020 that Sinclair Broadcast Group had reached a naming-rights agreement with Bally’s Corporation. Sinclair owned the regional networks, while Bally’s supplied the name through the partnership. The agreement brought a recognizable casino and entertainment brand to the networks, but Bally’s Corporation did not become the owner of the sports channels simply by lending them its name.
For viewers, the change was most visible on screen: channel logos, graphics, websites, and other branding were updated. The channels continued to carry regional sports programming. A new name did not mean that every team moved to a new network or that the networks all started from scratch.
Why did the networks change their name?
The rebrand followed a major shift in the ownership of the former Fox regional sports networks. In 2019, Sinclair Broadcast Group agreed to acquire the networks from Disney. Disney had acquired them as part of its purchase of much of 21st Century Fox, but the U.S. Department of Justice required Disney to divest the regional sports networks because of competition concerns.
Sinclair completed its acquisition of the networks in August 2019. At first, the channels continued to use Fox Sports branding under a licensing arrangement. That branding was temporary: Sinclair would need a replacement name when the agreement ended.
The Bally’s naming-rights partnership provided that replacement. It also gave Sinclair’s regional channels a shared identity. Instead of audiences seeing a collection of networks bearing the Fox Sports name, the channels would be presented as a connected group under the Bally Sports brand.
The difference between Bally’s Corporation and Bally Sports
The similar names can be confusing. Bally’s Corporation is a gaming and entertainment company. Bally Sports was the brand used for regional sports television networks owned by Diamond Sports Group, a subsidiary of Sinclair. The naming partnership connected the two companies commercially, but the names did not mean they were the same business.
That distinction matters when looking up a channel, a team’s broadcast, or a company announcement. A statement from Bally’s Corporation about its casinos, for example, is not automatically an announcement about ownership of a regional sports network. Likewise, sports-network business news may involve Sinclair or Diamond Sports Group rather than Bally’s casino operations.
What changed for fans in 2021?
The main change was the networks’ identity. Viewers saw Bally Sports branding replace the Fox Sports regional branding, and digital services and promotional materials were updated to match. The underlying purpose remained regional sports coverage, including broadcasts of teams whose games were available on the relevant local network.
Local availability depended on the network, the team’s broadcast arrangements, and a viewer’s location and television provider. The rebrand did not make every Bally Sports channel available nationwide, nor did it guarantee that every local game would be shown on every streaming service. Fans still had to check their provider’s lineup and the broadcast details for the specific team and game.
The channels’ schedules and team rights were also distinct from the branding deal. A name change alone did not create new rights to every team or determine how long a particular team would remain on a network. Those details depended on separate agreements and could change over time.
What happened to Bally Sports after its launch?
The Bally Sports brand did not remain the networks’ name indefinitely. In October 2024, Diamond Sports Group began transitioning its channels to the FanDuel Sports Network brand through a naming-rights agreement with FanDuel. The change marked another chapter in the networks’ identity, just a few years after their launch as Bally Sports.
That later rebrand does not change the answer to the historical question. Bally Sports began on March 31, 2021. It was the name used for a period by regional networks that had previously carried Fox Sports branding and later moved to a new brand.
The company behind the channels also faced significant financial challenges after the Bally Sports launch. Diamond Sports Group filed for Chapter 11 bankruptcy protection in March 2023. That proceeding concerned the company’s finances and business operations; it did not change the original launch date of the Bally Sports brand.
Because network names and ownership arrangements can change, fans researching a current broadcast should confirm the latest information with the team, the network, or their TV provider. Historical timelines are more straightforward: Fox Sports regional networks were rebranded as Bally Sports in 2021, and the Bally name was later replaced on the networks.

How to verify the launch history
For company history and current network details, start with official announcements from the organizations involved. Sinclair and Bally’s Corporation announced the naming-rights agreement in November 2020, while Diamond Sports Group and FanDuel announced the later branding transition. These primary sources help distinguish the date the Bally Sports name debuted from the earlier sale of the networks and the subsequent change of name.
It is also useful to check the date of any article you find. Older channel guides may list a network as Fox Sports, while information from the Bally Sports era may use a Bally name. Later listings may use FanDuel Sports Network. The different labels can describe the same regional channel at different points in its history.
