Major League Baseball is the latest of sport’s big behemoths to strike a deal with a live-streaming platform, agreeing to partner with Facebook for the upcoming season.

Available to a US audience on the Watch tab, which has yet to be rolled out in the UK, MLB will have 25 games seeded on the platform, starting with the Philadelphia Phillies taking on the New York Mets on April 4th. It is reported that Facebook will stream its live games mostly on Wednesday afternoons in the US.

Despite the rights to the live action taking in only the one territory, this is still an important development for a worldwide audience. As part of the deal, Facebook will host MLB’s dedicated channel on Watch in the US and stream their non-live content such as on-demand highlights packages – they will be available around the world. This marks a new development in Facebook’s plans for Watch.

We are still waiting to see if the much-heralded new feature will be a staple of the social media platform’s worldwide strategy, and if they do roll it out in territories other than the US, what form will it take? Publishers appear to be toning down their Facebook Live content, but that doesn’t mean that numbers are declining – for the right content an audience is definitely there, but it feels like it’s now time for Facebook to take a clear path on what its plans are for its video content.

Over the last few years, we’ve come to understand that it’s short-form content which works on the Newsfeed, mostly because of the sheer amount of content to sift through. A mantra of keep it short has led to what we now see every day on our phones: short-form, often junk, content. But if Watch does become a staple, everyone will almost certainly need a new strategy for the content they put on there. Publishers, content creators, leagues and teams will all need to see what culture grows up around the new feature, and how audiences will take to it before they take the plunge and put their content there.

One thing’s for sure, though, Facebook is still thinking about live sport, and still seems to see that as a draw to bring people to its platform. It will be the content created around that, though, which determines what happens next.

To go alongside that live content and highlights, will we see hour-long documentaries about the league’s history or its fan culture, creating more of a Netflix style output? Or maybe chat shows and debate shows? Or will the platform veer more into YouTube territory, becoming a place for shorter video clips instead?

These are the questions that we’re waiting to see answered. And as sport ventures more and more into documentary or longer-form content, through social video and podcasts, figuring out what Facebook wants for Watch is going to be another vital cog in most creators’ process.
