In the individual formats, the positive story for digital was reflected across the board. Notably high growth was recorded for digital radio ad formats, with a year-on-year rise in Q3 of +25.1%, and in VoD TV at +11.5%. Regional digital newsbrands witnessed growth of +10.9%, with national digital newsbrands measuring +3.7% growth, and digital magazine brands +1.5%.

Discussing the findings from the report, Stephen Woodford, Chief Executive at the Advertising Association, said: “UK advertising continues to perform strongly, now delivering its twenty-first straight quarter of growth and demonstrating the commitment of British advertisers to investing in the growth and success of their businesses.

“As the clock ticks down to our departure from the EU, it is crucial the Government provides the certainty we are all seeking in business. We are predicting continued adspend growth of 4.6% in 2019 and an agreement with the EU that keeps disruption at a minimum and keeps trade and talent flowing will greatly help this growth. UK advertising is the best in the world and we need a deal that ensures we keep it that way.”

James McDonald, Data Editor at WARC, said: “Our projection of 4.6% growth in the UK’s ad market this year is firmly based on a business- favourable outcome from the EU withdrawal agreement, and would mark a decade of continuous expansion since the last advertising recession.

“Further, a preliminary estimate of 6% growth in advertising investment last year represents a faster rate of expansion than was recorded in 2017, and is therefore indicative of an industry in rude heath. This is particularly true in relation to digital ad formats, all of which are currently forecast to attract higher levels of investment in 2019.”
