Ericsson's Networked Society Program has produced a second documentary, which is available for viewing by ReadWriteWeb readers a day before it is released publicly. The documentary series and program are attempts by the Swedish telecom company to investigate larger ideas, ones that affect how technology is created and used. Here's how Ericsson describes the focus of the latest film.

"The world population is expected to soar to more than 9 billion people by 2050, with roughly 70% living in cities. At the same time, ICT is extending its reach. These parallel trends are intersecting at a time when the world faces serious economic, environmental, and social challenges in achieving a more sustainable development. "Thinking Cities" explores the challenges and opportunities of urbanization in the Networked Society. To produce this film we interviewed some of the world's leading city thinkers including: Geoffrey West, physicist and professor at Santa Fe Institute; Mathieu Lefevre of New Cities Foundation and Carlo Ratti, Director of MIT Senseable City Lab."

When Keith Jones and Deon Maas first started trying to pull together the footage, sources and sound for their documentary, Punk in Africa, they found it slow going. It was only when they started leveraging a dedicated Facebook page and other social media tools did they start to make headway. And make it they did.

Thanks to social media, the film-makers were able to pull together footage and photos and accounts of the birth and young adulthood of punk in Southern Africa, along with the events, strife and social movements that fueled it (and that it fueled in turn). Some of the footage - including accounts of the tumultuous political and social conflict in the countries - had not been seen in 30 years.

This year the movie industry made $30 billion (a third of it in the U.S.) from box-office revenue. But the total movie industry revenue was $87 billion. Where did the other $57 billion come from?

From sources that the studios at one time claimed would put them out of business: Pay-per view TV, cable and satellite channels, video rentals, DVD sales, online subscriptions and digital downloads.
