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.
