It's going to vary on the subscriber requirement. Some have one and some don't as long as you have the views. The main reason, as far as we can tell, seems to be as a backup metric to dissuade view botters from applying. (it's gotten harder and harder for people to bot subscribers) Like we said though, as long as you have the views and they don't think there's anything shady... the subscriber requirement is moot or will go out the window fairly quickly!It's just that that i only have 66 Subscribers and next to 70000 total views and the big networks often want over 1000 subs, Right?
As far as what network... just do your research and then select the best network for your channel and goals! Research 10 or more and then narrow it down to a handful and apply to those.
Hope that helps and good luck!
