How the British Television Industry works (Ongoing thread)

Given this is where the bulk of discussion relating to TV will pop up, I figured it was time to create a thread devoted to accumulating knowledge and combating common misapprehension and rumours. This'll be an easy and fun little resource for anyone curious about how your favourite programme(s), be it Who or otherwise, see the light of day, and maybe even be of use if you are currently studying for a career in the field of film and/or TV (there's crossover aplenty in how they operate).

First, an easy little introductory article on the TV business and how ´this' becomes 'that':

Next up, a video from Creative Skills on what a producer does:

An article from Vulture on the hard work of a crew. This should help clarify any idea of glamour:

If anyone finds other links, resources or fun little articles, by all means, respond and post them here.
Like I said, I want this to be a wealth of knowledge, accessible at a click.
