I'd say the roll of Mark Ashley when it comes to DVDs: 2003-2010. It was less ink, more production value and a lot more BTS, BGG and there were mansions involved in the settings. These areas of filming stated golden era, so it's not that hard to figure out.
I missed what might be the golden age of internet porn: late 1990s-early 2000s. Many sites had been shut down or sold to corporate networks before I arrived.
