+At the beginning of this era, in 2019, GreatApe wasn't called “GreatApe” yet.
+But the idea of it being a form social-media platform, with rooms that people joined, where they had video or audio conversations, was already there — and had been there since 2017.
+
+In actuality, we had thoughts on a number of different for applications for the technology we were developing —
+but for the sake of telling a story about _GreatApe_ we will focus on just this one appication.
+
+We had some constraints for the application —
+
+* it must to work in a web-browser,
+* the user should must _not_ have to install anything to use it,
+* it must be privacy-protecting (from people outside the conversation),
+* it needs to make the cost of streaming video in real-time negligible.
+
+These constraints came from the industrial-research we had done prior to the start of this research-and-development.
+(More on that later.)
+
+Back in the late 1990s to mid-2000s, when the core of technolgy was first invented, it wasn't yet possible to accomplish this.
+But, decades later — with the addition of the WebRTC technology to the web-browser, all of a sudden it looked like it might be possible.
+
+The goal was to recreate the tree-stream technology which invented in the late 1990s to mid-2000s — but to this time re-create it to work within a web-browser.
+Thus started the research-and-development.
