There have been (and still are) many networks among YouTube channels already. Some like Linux Tech Tips have a number of channels and a pretty large team. Others are more corporate and adopt creators as they get popular, but the actual network/org is not as obvious since they kind of act in the background, getting sponsors and distributing funds and services to their affiliated creators. I just don't see anything off-YouTube as gaining critical mass in the near future though.
