At the end of last week Steam.tv came into existence and appeared so quickly, but not before the Internet noticed that Valve quiet had launched a new streaming website ̵
If you're looking for Steam.tv now, you'll find a live broadcast of 2018 Dota 2 International, and some nice, simple features. You can scrub through the power as you can during YouTube's lifestream, and even better, the team matches are highlighted on the timeline so you can jump to the highlights. You can also log in with your Steam account and either join the main chat or create group clubs with people from your Steam friends list.
Seeing pro Dota 2 is of course not where the valve plans to stop using Steam.tv and i-client broadcasting. "This Dota 2-centered update to Steam Broadcasting currently contains some custom elements to support The International," reads Valve's blog post. "After the tournament, we plan to expand Watch Party support for all games sent to Steam and reveal a new Broadcast Steamworks API to Steam Partners."
With such a large library of games and massive user count, Valve has a lot of power to improve livestreaming here. If it can make streaming more convenient through trusted Steam client tools, and also give developers a lot of space to customize how their games are streamed (the Dota 2 cursors are probably only the beginning), it can be a real force in the scene. Somewhere Ventil does not have much experience, but is in Twitch's revenue plans, although I'm not sure Valve can figure out how to make and share money, as it does at Steam Marketplace (and just by selling games, of course which streaming promotes).
We watch new developments as Valve expands its broadcasting platform.
