We are excited to announce that we have entered into an agreement to merge with ironSource, harnessing the ironSource’s tools, platform, technology, and talent to form an end-to-end platform that enables creators to more easily create, publish, run, monetize, and grow live games and RT3D content seamlessly.
Learn more about what this means and how it will benefit creators worldwide on our blog
Update November 7, 2022:
Nice 
Is it means that over time Integrating Unity Ads will actually become integration of IronSource?
I hope this collaboration will yield into a better experience for the user.
I hope that UnityAds will continue to serve ads from a centralized server and unique ad-media-player in-game.
Congrats! I’m sure this is a good thing for many - will be interesting to see what it means for us moving forward (i.e. eventual availability of new features, tools, services, etc.).
I noticed that I can not see v4 of Advertisments package in Package Manage. I can see v 3.7.5 which is old.
Unity 2021.3.6.
A couple of days ago, I could see v4
P.S. I can only update from v3 to v4 manually with editing package manifest file and indicating the last version.
So, will Unity Mediator be deprecated? Should i implement ironSource instead?
Don’t care about this at all. Where’s the blog post about what happened to Gigaya?
This ironSource?
if IronSource has SuperSonic as publisher… won’t this mean that other publishers won’t want to work (or will decrease the likelihood that they’ll want to work) with Unity made games?
also, this is a good question… will other forms of monetization will be forbidden/discouraged from working with Unity? because… if there’s only one way that the devs can monetize their games through, that gives that way a lot of power over the conditions it might impose
With 1000 employees despite their focus, they are a fairly large player and things like those are unfortunately bound to happen 
Don’t think that results in more risk than other add providers.
Also that software in question was apparently discontinued in 2015.
Unity is on thin ice, must not interfere with game dev with this. Must remain purely optional.
It’s good that they tend to keep acquired companies fairly separate then, isn’t it? 
Think it’s meant complementary to the game services they already offer, just mainly focused on adds and -related analytics. So that naturally is fairly optional.
Unless they decide some day to enforce adds for games made with the free version of the editor, but think that would be too risky to end up with bad reputation even for them.
And never, ever bundle any adware/malware process with unity editor install. It will not be possible to recover from the Dev exodus to Unreal. you have been fairly warned. Make sure you understand how Devs think.
please understand how little you mean to a corp and learn to champion your own interests. Some of us know what’s happening.
Hi, hello, is there a version of this blog post not written in full blown nonsensical marketing-speak, or written by a human?
Of course not.
The blog stopped being made for humans long ago. Nowadays is for investors™
This is being described in Unity’s press release as a “merger”, not an acquisition. Based on this, I would expect ironSource to be a more integral and crucial component of Unity.
Yeah, they better keep this separate. Having to explain to gamers why your game triggers a malware warning would be a deal breaker for most devs.
This announcement is already making the rounds in social media and as expected people are not taking it as calm as we do.
Absolutely repulsive.
Heh well looking at their stock price it went over just as well with that crowd.
