Newspapers to video

I’m seeing what seems to be an exponential increase in people watching TV shows/Movies/YouTube videos while riding the train or bus lately.

Are most people downloading this content to their device before watching it? Or obliterating their data plans?

For those that are downloading at home before heading out: it harkens back to Netflix of old, where you had to receive TV seasons on DVD, one or two discs at a time. Finish those, and you have a lonely (and at times agonizing) wait until the next disc arrives. Or in current times, until you reach a suitable WiFi network to download more content.

It also makes me wonder how people have allocated their device space for this content, when it seemed that the popular complain was devices filling up.
