I now regularly rely on the Internet to catch up on television shows and movies. Technology has finally caught up so as to provide a sufficiently pleasant experience - e.g. high resolution, quick download time, etc.
But the decentralized nature of the Internet is far from conducive to easily finding shows. There are the official websites such as NBC.com and ABC.com, the officially endorsed aggregators such as Hulu, the pay-for-subscription services such as Netflix, the user-generated hubs such as YouTube, and then there are the bootleg sites that offer lower quality but greater diversity. The complexity is further complicated by the fact that there seems to be very little logic behind which shows end up where and for how long.
Clearly there is a need for some central, interactive, and highly comprehensive Internet-based TV Guide - and there are a few in development/early-stage rollout. But what's even more important is the need for some form of collective, marketplace understanding - potentially driven by consumers - as to what, when, where, and which content is expected.
