In the modern world, watching TV shows isn't what it used to be. Back in the old days (or the present for some), shows simply existed at a certain time and you tuned in when they aired, and then they were cancelled and then you never heard from them again. Today, though, it's not uncommon for most viewers to discover a show a few seasons in and then find their way through the backlog of episodes.
If you're anything like me, you text constantly. There are times, however, that I put my phone down and hop on the computer to do some more in-depth tasks or just enjoy some good, old-fashioned big-screen browsing. When I'm doing that, it's usually a pain to receive a text message, have to dig out my phone, open the messaging app, and use a tiny keyboard to reply, even though I'm sitting at a much larger, easier to use keyboard.
