"The UK advertising market continues to grow from strength to strength following a 6 per cent increase in sales last year to reach £4.91bn – the fifth consecutive year of growth to be enjoyed by the sector.
Compiled by Thinkbox the latest batch of figures was boosted by the growth of online brands such as Amazon, Google and Netflix with online brands and services doubling investment in the sector to over £400m since 2010.
The market was also given a lift by 800 new and returning advertisers who took linear spots, sponsorship, broadcaster VOD, and product placement packages in 2014. Their combined output saw the average commercial TV viewer exposed to 45 ads whilst watching 2 hours and 25 minutes of content each day."
