YouTube and FACEIT have announced a partnership deal giving YouTube "multi-year" exclusive broadcast rights to the Esports Championship Series for an undisclosed fee.

"YouTube offers fans of the ECS an unmatched online viewing experience,” FACEIT Chief Business Officer and co-founder Michele Attisani said in a news release.

“YouTube is by far the most watched platform for gamers in the world and continues to innovate and lead on video technology, making it a great place for us to call our new home for the Esports Championship Series.”

ECS games will start streaming exclusively on YouTube on March 25 with the start of Season 3's promotion matches.

It's unclear if YouTube's purchase of ECS' broadcast rights only includes the English broadcast, since the ECS Season 2 finals were also broadcast in Russian, Polish and Portuguese. The news release also does not specify how long the "multi-year" deal is.

The news follows YouTube's purchase of the English-language broadcast rights for ESL Pro League seasons 5 and 6.

“This is our most significant investment into esports to date and illustrates our continued commitment to growing esports with the hundreds of millions of gamers watching YouTube each day,” YouTube's Global Head of Gaming Content Ryan Wyatt said in the release.

“The ECS revenue sharing and co-ownership structure reinforces our belief that all players should have a voice. We know the CS:GO community is already watching clips, highlights, and rebroadcasts on YouTube, so we are excited to be able to bring them all this same action live”.
