What if Riot started allowing advertising

When the pando remover popped up in my client loader, my sister was like, "Is that an Ad???"

And I thought what if Riot introduced pop up ads in the client or you have to watch a video before pressing play. (THE $$$$$$$$$$)

And, jokingly, what if Riot played 30 second vidoes in middle of team fights.

Then my friend though placing advertising signs around the rift.

What you guys think if Riot does that? (Especially for the $$$$)
