Let's do a run down of my monthly online spend.
Hulu premium: $11.99
HBO now (or is it HBO go?): ~$12.99
Sling TV: ~$50
Google play (includes YouTube red): ~$13
Amazon prime (also used for the Amazon TV shows): ~$9
A random Twitch show that I patronize: $6.66
Wikipedia: I donate $10/year, so let's say $1.
So, roughly, ~$125/month.
I use Tumblr heavily and the ads piss me off, but the moment they offer a premium ad-free option they can shut up and take my money.
