Is the income from sponsor are directly proportianal to audience in linear way or dynamic logrithmic way?

Yes, the sponsor's bonus is proportional to your TV's audience, but I don't know how much a sponsor earns for a level 10 TV with 5 million viewers?

The first has just 1.3 million

junior: Le premier a peine 1.3 millions

How many spectators are you losing by taking it?
