Iran's religious and political leadership view Youtube as a great evil and are launching an alternative called Mehr. Mehr allows registered users to upload videos and allows anyone to watch posted videos (like Youtube). Of particular interest may be the content provided by the national Iranian broadcaster IRIB.
Iran is increasing its control on information and is even expected to lauch it's own Iranian Internet (or should we call it a national intranet) in 2013. We have read reports from activists that many Iranian's, thirsty for uncensored information, have started using technologies (like VPN, TOR,etc) to bypass controls. It is expected that the Iranian officials will slowly but surely implement stronger inspection tools to prevent bypassing of their controls.
