Yeah, OnLive did it back in 2003!

Wikipedia says the company was founded in 2009. I remember trying it in 2010 too.

Ugh, the google smartbox pulled '2003' from somewhere. You're right, it was 2009.

Which three? Did they actually work with reasonable input latency?

I thought of OnLive, Shadow, and Geforce Now.

The only one of those I'd used was Geforce Now, and found it very similar to Stadia wrt latency. Stadia had a much nicer interface, though.

PlayStation Now already existed for years as well.

Which they got through their acquisition of Gaikai (considered a competitor of OnLive).

The discussion was about innovative products. An already explored idea, but executed properly, only counts as innovative if Apple does it. And even then, it only ran for a couple years, so even if we want to give points for taking an idea and making it work, they don’t pass there either.

Stadia worked much better than the competition. It was the first time that cloud gaming had no tradeoffs. Definitely a lot of innovation behind the curtains.
