I'll drop my two penneth in, and say its changed in much the same way as the delivery method has changed from VHS / DVDs to online only...
Take my ex wife - Over 600 scenes for professional company's under her belt. But she would never have referred to herself as a 'Star'... But she was obviously a star to the sheer amount of company's that would shoot her again and again, over and over... But why?
Because she always turned up on time, was clean and sober and went the extra mile to make sure she gave a great scene... WHICH SOLD...
But she wouldn't have called herself a 'Star' - Just a 'Professional' - However we would often come across girls at conventions running about saying they had shot 10 scenes, so they were a 'Porn STAR'...
But like I said, the landscape has changed now - Girls shoot themselves and upload to only fans... So the metric is 'The Amount Of Money' they make... It isn't the amount of rebookings and scenes (& by default the money they paid her)
So as such, I'd argue that the traditional pornstar doesn't exist these days - In much the same way as VHS doesn't exist either... Anyway, who really cares?
Years of experience have told me that the louder the girl shouts that she is a 'Star' - I can guarantee you, that means the further away she is from being one...
