One of my favorite YouTube channels uses the fame and funding to take on dog grooming jobs no one else is able to, or is able to devote enough time and detail to.

There's also an explosion of channels where professional landscapers and pressure washers do the occasional free job on a house in desperate need while recording it for YouTube. It's great background TV and likely more effective than any kind of paid advertising.
