well Meltzer said this for UFC 130 which got 300k buys ... he also made another reference to the international/domestic market for a ppv in a later event but I forget which: "The strongest markets for UFC 130 look to have been Las Vegas, Calgary, Toronto, Phoenix, Los Angeles, Melbourne, Sydney, Edmonton, Halifax, Winnipeg, Vancouver, Ottawa, Montreal (interesting to note that market doing well for a non GSP fight),Honolulu, Sacramento, San Diego and Orlando." 17 cities 9 canadian 7 US (or do we count Hawaii?) 1 Australian I understand this is matched by bar reports on the UFC website somewhere but I haven't seen it. If you splice the numbers from that it's quite clear Canada is the strongest market by a decent bit. Also worth noting that for UFC Rio Meltzer commented that the US market dropped 15%. When all's said and done these events are likely getting less than Toney-Jones got from the US. Meaning the UFC's domestic PPV numbers are about the same as a poor boxing PPV.
