I think the content-advertisement blend tends to oscillate. That means that things like infomercials are successful only until people realize that they are being flooded with information they would rather not have.
Once viewers become aware that they are viewing an ad, they feel misled by the provider: tricked into watching an add. At that point, negative sentiments toward the provider, something that the provider wants to avoid.
At that point, structures like Google SERPS, where the advertisements are separated from the content, and clearly marked as "sponsored" become pleasantly successful.
I suppose that the complexity of the internet enables a blend between content and ads in ways that wasn't possible before. That could push the metrics in a way that would enable ads profitable in more situations.
But I don't think it will become an unmonitored variable.
