Although the channel was based in the United States (its headquarters were located at University Research Park in Charlotte, North Carolina), Speed ceased being available to most American viewers as a standalone network with its own original programming on August 17, 2013, when it was replaced by the general-interest sports network Fox Sports 1. An "international" version of the network, now known as Fox Sports Racing, concurrently launched in Canada, the Caribbean and the U.S. territory of Puerto Rico to replace the domestic feed, airing archived Speed programming and live simulcasts of motorsports events carried by Fox Sports 1 and Fox Sports 2 in the United States that would be otherwise unavailable to international viewers.
