Japanese Promtion's PPV's

[carpetbeggar]

Question about how the PPV's work over there in the last 10 years. How are they scheduled for say the big companies like Noah, NJ and AJ? Is it like WWE and TNA where there is a tight schedule of PPVs with them doing one a month?
Also what is televised on regular TV/cable and PPV? Are a lot of the big shows just available through mail?
Are the ppv's only available in that part of the world or do any North American or European cable companies offer any of the Japnanese Puroresu PPV's on their service?
Which promotions offers PPV's and DVD releases with English commentary? Does Noah still have English commentary versions of their shows?
Thanks

Well, New Japan didn't start doing PPVs until 1999. All Japan didn't do PPVs until 2002. Japanese promotions don't do as many PPVs a year as American promotions like WWE and TNA do.
