Being a world wide religion, they do not have to put a whole lot of content. They can just re run whatever they have. Different languages and different content based on location. I used to toy with FTA TV and I've seen some middle eastern channel (talk about indoctrination) where the same old man talks all day in the same channel, 24/7.
They make it sound so huge. I work for an internet company and we have our own TV studio. It only took 5 people to put it together. Now if you count all the "servants" that bring coffee for the GB and fan air on them.
