I know they were atleast doing it in 2014 because I remember seeing the little stage they had set up for it in person and 2014 was the last year I went to E3. That was after Nintendo made their treehouse stuff a thing (iirc) but it isn't a new thing this year by any means.

The treehouse stuff started in 2014 as well:

In 2014, they started to have livestreams on Nintendo games on top of Nintendo Directs, due to the success of their E3 stream

 

If anything, the current treehouse seems to have been inspired by Sony Sony did livestreama first.

That may be, I honestly was always focused on Sony stuff when I was at E3 so I only vagely remember treehouses as a thing but not when they started.
