WOW got some ink today! They're still taping and apparently their new goal is to be a "digital series." (...which probably means there have been new episodes out there for months with me being blissfully ignorant about it.) What you can REALLY take from this you need the writeright author for the writeright article. We got that here.
MGM just picked up the rights to distribute internationally WOW a few weeks ago, so either Lucha Underground has been successful enough in that way that they want more, or they figured out it'd be cheaper just to buy wrestling programming than help pay for it. Or if they just wanted to have the (surely cheap rights) for WOW in case GLOW did take off.
