HBO and ESPN have joined forces in a multiyear deal that will see the pair collaborate on boxing programming and marketing. The pact means they will partner on support for pay-per-view boxing events and share programming content, cross-promotion elements, highlight packages and other assets to be featured across multiple platforms. As part of the agreement, ESPN and ESPN Deportes will have access to key content and information surrounding marquee HBO PPV events, including fighter interviews. The deal will kick off almost immediately: ESPN and ESPN Deportes will televise the HBO all-access series 24/7 leading up to HBO Pay-Per-View fights; on Thursday, ESPN2 will air the two-part 24/7 Julio Cesar Chavez Jr-Sergio Martinez fight set for Saturday in Las Vegas.
