Yeah because fans have become so disillusioned with the product and fighters of today, that they have had to sub to fightpass so they can watch all the old days, when UFC was at its best. I expect the number to get bigger as the cards get worse and worse. People need something to hold on to and enjoy.
I did have fightpass for a month, so I could watch some older events, although I have a lot of the old events on VHS but no longer have a video player. The VHS versions are better though because nothing is cut out, the fightpass cuts a lot out. Like when Tank Abbott murdered Steve Nelmark, on fightpass it just cuts off when Big John raises his hands, but on the VHS version they show Nelmark out cold for ages and they can't wake him up and was still out cold on stretcher.
Expect fightpass to grow as fans stop watching current UFC, but still love UFC so they can go back and watch all the amazing events of yester year. Very few people use it to watch the fightpass prelims and all that low level garbage we get today. Nostalgia, the peak era's will never be forgotten
