• Hitler Is Very Upset That Constantin Film Is Taking Down Hitler Parodies – After Marmite ordered the BNP to take out images of their product from their site, another strange copyright take down notice has been served this week on hundreds of un-suspecting parody film makers: Constantin Films, makers of the (outstanding) film Downfall, have served notice on many parody film that use the scene of Hitler in his bunker to convey everything from frustration at the new iPhone, leaking a list of BNP members and anything topical/mundane/silly. Parody falls into 'fair usage' in many settings, and the web memes gave the film a breath and life that many German films could never have. It seems a strange move on the part of the film makers, particularly when it's become a 'genre' in itself (this is publicity independent film makers cannot buy), and further shows the divide between how some copyright holders perceive their work should be used, and the means people are choosing to re-create and use their works.
• Altimeter Report: Social Marketing Analytics (Altimeter Group & Web Analytics Demystified) – A summary of how social media can be measured, and what analytics tools can be used.
• First Take Analysis: Facebook’s Crusade of Colonization – The irrepressible rise of Facebook continues with yet more changes aimed at opening up the platform, mainly to the benefit of developers and marketers, but with some controversial loss of privacy (basic data about your locations and interests will now be visible to all, unless you choose to remove it). Jeremiah Owyang gives a roundup of the raft of new technical features, and how they threaten to compete with other social services including Google. Facebook are positioning themselves as the personal hub online – even making moves to compete more seriously with email and document sharing services.
