Where there are multiple departments involved a press release can also be a source of competition between areas of the Commission and Commissioners themselves. This also leads to an unusually high number of press releases, 1907 for 2006, and is seen as a unique product of the EU's political set-up. The number of Commission press releases shows a decreasing trend. 1768 press releases were published in 2010 and 1589 in 2011.
But it only has data for 3 years, and ends in 2011. Has the trend continued? And if there is a trend, have there been any published analyses/hypotheses as to the purported reason for it?
