The WPP-owned media measurement and management arm GroupM has recently published a UK-specific report on the dynamics of advertising spending across all media in 2014-2015 years. The company predicts that this year the ad spending will show a 6.3% increase in the face of a slightly lower global figure of 4.5%. This is the fastest growth of ad market among all the researched developed economies. In terms of financial value, the ad spending will account for a total of £14.9 billion ($23.3 billion) in 2014, and £15.7 billion ($24.5 billion) in 2015.

Latest report called «This Year, Next Year» by WPP-owned media management from GroupM, forecasts that global media spend in 2014 will reach $534 billion, a 4.5% increase over 2013. The ad spending will increase 5% to $560 billion in 2015, GroupM predicts. Both figures are very close but slightly fewer than the calculations earlier revealed in July by eMarketer.com.
