Just what demographic is YouTube or for that matter the cyber highway?

As I get ready to shove off and depart my mortal coil for another day, I watched the speech from Ted Cruise from the Republican National Convention on YouTube. While the speech was interesting enough, what was even more so was the chat going on along with the speech on PBS's YouTube channel. I'll bet you a root beer that there wasn't more than two people there over the age of maybe 23 on that chat. Able to vote, but have no idea of what they're doing. As for me I'm remaining on the fence about Trump, and all. I was all near leaning towards Trump, but his Vee-Pee running mate from Indiana, does not impress me any, and in fact I'm a bit spooked by him. While Trump is okay and might make a purtty good President, if preytell but if something should happen to the Don, that idiot from Indiana would be President, and if that happens, many of you will pray to get old Obama back. 
But then I wondered too, what age bracket or demographic is the target of the cyber highway and/or YouTube? I'd again I say and I'll buy you a root beer if I'm wrong, but I say no older than 50 and that's stretching it a bit. Plan on being on air on Livestream with Coast2coast fm, just depends on if my body will take it. Been busting balls on a wildfire and putting in days at the shop, and while the body says yes the mind, and in consideration of my immediate neighbors am staying quiet overnight.
