Is technology really that behind? I mean redtube/et al are some of the largest websites out there and the blog posts seem to show a pretty high level of technology behind them although with a larger focus on cost than most startups.
99% of adult sites run on single servers using out of date PHP/MySQL scripts. Sites like RedTube, etc use newer technology, like at Confoo a dev for YouPorn talked about their stack and they use Symfony, Varnish and Nginx.
True, but behind these tube sites stays [1] Fabian Thylmann and his [2] company. He is considered as the biggest disruptor who revolutionised the business. The whole story is something like Napster and the record labels, but slightly different.
