M&A activity fell in the first three quarters of 2013, from 933 deals worldwide in 2012 at a value of $46.08bn to 854 deals this year at a value of $27.6bn. However, the changing nature of the industry means companies will be forced to change strategy to move forward, and improving economic conditions should make next year a more stable environment.

An independent auditor has identified serious weaknesses around a failed digital project which cost the BBC GBP100m. Conceived in Nov 2005 to "fully prepare the BBC for the on-demand digital world" the DMI initiative was initially given the go-ahead in December 2007 with a budget set at GBP81.7m. In February 2008 Siemens was awarded GBP79.8m to take the project on only for it to be taken in-house again in July 2009. Yesterday's report found that in June 2012 a BBC review said that of 12 DMI "functions", only one was in live use "but required a period of stabilisation".
