There are many programs where it is necessary to watch video to get reward but I do not know about such programs on blockhain and payment in tokens.
Do you mean games where gamers can watch promos to get in-game currency? The main problem for this project that I see is to make their token interesting for people. Otherwise, they won't use this program at all.
We want to take the focus away from people promoting their in-game currency, we want to focus on the products themselves more importantly.
We will ideally have where gamers can actually see and learn more about the game.
Hopefully something similar to this Cryptokitties video -
