How to programmatically find out what channels are part of a given YouTube network?

Question

Looks like there is no official YouTube API to find list of YouTube networks or what channels are part of a given network. Any ideas how to find that information?

Answer 1

I don't know if this is the way sites such as socialblade or channelmeter get the networked channels. But this is the way i did it.

Say i visit this video link: http://www.youtube.com/watch?v=_8AZT40gH5E

In the meta tags information of a networked channel, there is an attribute (As example) which actually specifies the network that channel belongs to. So what i did was one video from the channel i'm working with, and use a small function like this:

$tags = get_meta_tags("http://www.youtube.com/watch?v=_8AZT40gH5E");
echo $network = $tags['attribution'];

And you have the Network the channel is associated with.
