Whether he knows it or not, he's a very clever man.
With the shift from broadcast TV to "on demand" content delivered via the Net, the demand for content such as Dave's EEVblog and PhotonVids will increase significantly over the coming years.
The "stars" and "celebrities" of the future won't come from Fox, CBS, or whatever -- they'll come from cyberspace and grow like wildfire due to the massive promotional effects that social media can deliver.
The fact that the mainstream broadcast media are already taking note of, and an interest in, PhotonVids is proof of this. They know that these new "celebs" are a growing phenomenon.
First we had "reality TV", which was in fact far removed from reality but allowed the broadcasters to bring "personalities" into programming in a way they could never have done before (and at a very low cost). Now the audience is growing tired of that artificial "reality" -- because they can get a fresher, less "edited" version of it online.
The mainstream media know they're losing out to these self-made celebs and will soon be working hard to pick up on the success of folk who've "made it" in cyberspace with offers to deliver their content through "real TV". I don't know that such arrangements will work - but it does show the power of an individual who's able to create and grow a brand that people enjoy.
Just as recording companies have become increasingly irrelevant with the rise of the Net and movie studios are also finding themselves faced with increasing competition from "independent" producers (eg: ), so broadcast TV are finding that independent content producers with a strong brand have the potential to significantly eat into their market share and revenues.
Go the independent content creators!
