The Blood-Horse is a news magazine that originated in 1916 as a monthly bulletin of the Thoroughbred Horse Association. The corresponding online website publication is Bloodhorse.com. In 1935 the publication was purchased by the American Thoroughbred Breeders Association. From 1961 to 2015, it was owned by the Thoroughbred Owners and Breeders Association (TOBA), a non-profit organization that promotes Thoroughbred racing, breeding, and ownership. The publication was issued by a subsidiary called Blood-Horse Publications from 2000 to 2015. In February 2015, the Jockey Club purchased a majority share in the publication. Long published as a weekly newsletter, the magazine became a monthly publication in April 2021, and the magazine and website are now published by a partnership entity of the Jockey Club Information Systems and TOBA called Blood-Horse LLC.
