Starting with comparing the two graphs, we can appreciate a visible similitude between the left blue curve and the right columns. So, is no doubt that the number of Global digital 3d screens are narrowly connected with global 3d cinema releases and, in particular, with live action films release.
For instance, if we focus on the 2009-2011 time range its clear that the global screen curve has experienced an astonishing rise since the live film’s introduction by cinemas, meanwhile, for the first four years, when there was not that kind of films, the curve was quite flat till 2008.
Moreover, Live action films which are represented by violet columns, have increased more than a seventh time in only four years, indeed.
In conclusion, also animation films are increasing during these years but more slowly than action film, which means that cinema’s customers have much interest in this kind of Hollywood production.
