We are very lucky to be living in this time. The variety of ways of watching video is simply amazing. Right now we currently have broadcast stations, subscription-based cable television, youtube free-for-all, high-quality vimeo, streaming ustream channels, and video podcasts.
Then we got things like chromecast to push video to tv. Apple TV and netflix to get stuff on demand. DVRs to record live tv with super-ease. We can watch videos on the train or in the park.
We can talk about tv online, live as it happens. There are a plethora of websites dedicated to analyzing episodes of all genres of television programming.
