MemeMolly is a great example of a Vlogger/content producer who is commercializing her audience equity on Youtube. She is the 4th most subscribed Canadian on Youtube. Here are two examples of her commercial nouse.
She recorded this music video clip for artist Ali Slaight, she helped to bring 40,000 new listeners to her music.
On MemeMolly homepage she has also given up her prime video position to the MyDamnChannel, a commercial channel sponsored by Southern Comfort.
On a side note; this is a few of the better channels that I am subscribed to on Youtube (full listing here).
