TOWID (The Only Way Is Digital)

2013 is clearly set to see digitisation continue apace, with analogue media being displaced by digital media which are typically cheaper to produce and distribute. That doesn't mean that analogue media, such as films shot on 35mm and distributed as 35mm prints to cinemas (each print costing £000s), will disappear, but that bit by bit the industry is moving over to digital content.
Here's some useful stats from this article, about Google buying a 10%, $50m stake in the video distributor Vevo (the joint Sony/Universal venture that you'll have come across if you've watched a few videos on YouTube, given how much of the music industry their artist sales represent):

Earlier this month the Entertainment Retailers Association reported that downloads of music, TV shows, films and video games topped £1bn in the UK for the first time in 2012. Digital music sales grew but revenue from physical singles fell by 44% year on year and albums dropped 11%.

The cinema industry and CD sales remain strong but, like newspapers, which are also seeing circulation declining rapidly as more people access their news online, may not have a bright future. The record set by Skyfall, 2012's Bond movie, may never be beaten: it became the first movie to take in over £100m at the UK box office by the last week in December 2012 (it was already the biggest ever UK cinema hit, and topped $1bn worldwide).
