Do you remember when you had to just watch whatever the television networks thought you wanted to see? And if you wanted to watch your favorite show, you had to wait ... a week! You know - back before you could pull a miniature television screen out of your pocket and watch anything anytime anywhere?!

Oh, how times have changed!

For example, YouTube says that people watch over a billion hours of YouTube video ... a day! Paid streaming service Netflix has more than 139 million users, according to a Paste article in April. And Disney is making news with its just-released "Disney Plus" streaming service, which is home to iconic movie brands like Marvel, Pixar, Star Wars and, of course, Disney itself. And don't forget about Amazon Prime and Hulu and iTunes and .... you get the idea.

Here's a look at some of the streaming service numbers. Mouse over or tap the graphic for more info.
