There was Joost in 2008, from Skype founders. Skype was originally P2P until Microsoft acquisition and killing this legally questionable feature - need to feed the big brother (: Joost raised ~$50M.

I remember it as it was one of rare apps built in XUL, the same framework as Mozilla apps (Firefox).

PriitK of Joost/Sykpe was also involved in the original Kazza. I've told previous stories of his involvement in a 1990s MMO spaceship game, where he recreated the original buggy/cheat-filled client (Subspace) and released the now standard replacement (Continuum).

Skype's call quality was great when it was P2P. Went downhill when it was no longer on P2P.

I distinctly remember living alone in my first apartment and trying to use Joost like a TV. It was a dismal experience.

Came to share this too. I used Joost at this time. Got me into watching the world poker tour on the platform and into playing poker and watching other live poker.
