If you think your digital media planners do well and your budget on Internet ads is spent wisely, think twice. Following Google’s ad viewability report as of November 2014, which suggested that about 56% of all digital ads paid by advertisers are usually never seen by consumers, the Luxembourg-based startup Oxford BioChronometrics has proved that this number is actually much higher.

The breast cancer awareness charity Coppafeel, founded by the disease survivor Kris Hallenga, continues its last year’s high-impact visual campaign in the U.K. This year the advertised material features a collage of 24 pictures of bare-chested women, with each image accompanied by the word they chose to describe their breasts. These posters, created by the agency Karmarama, will run on digital outdoor screens nationwide until the end of February.

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.

Havas Media Group along with the two research agencies Differentology and On Device Research have teamed up with Sky Media, advertising sales arm of Sky, to conduct one live and two lab experiments aimed at trying new methodologies in measuring mobile advertising effectiveness.
