Advertising on digital screens is the fastest growing sector within the out-of-home medium, with ad spend predicted to reach £36m this year.

The number of screens has steadily increased over the last few years to over 233,000 but the various out-of-home screen networks are all consumed slightly differently.

Some are 'watched' like TV, others act more like a digital poster and most lie somewhere in-between. Consequently the need for creative and media agencies to share their expertise and experience becomes even greater.
