Until the mid 2000s very few decent DVD producers were selling out to anyone online. The reason is simple, online couldn't or wouldn't pay enough to compete with what they were earning. Now that's turned around and offline porn is slowly dying for most.
For a cash rich company in online porn to ignore this is frankly, stupid. These offline companies have archives of great porn, a brand name that means something and the production know how to produce porn a step up from what most online companies do.
Online offers the knowledge of getting and selling to traffic.
The only question is the price or a deal.
