Global advertising spend is on course to grow 10.7% in 2024 to a total of $1.08trn – the strongest growth rate in six years and the largest absolute rise on record if the post-Covid recovery of 2021 (+27.9% year-on-year) is disregarded. The new forecast – published by WARC, experts in marketing effectiveness – represents a 0.2 percentage point (pp) upgrade on WARC’s last global forecast in August.
Ad spend growth is also anticipated next year (+7.6%) and in 2026 (+7.0%), culminating in a global advertising market worth $1.24trn. Global ad investment has more than doubled over the last decade and has grown 2.8x faster than global economic output since 2014.
Online on top
Building upon a solid performance for legacy media, pure play internet, which encompasses advertising revenue among online-only businesses such as Alphabet, Amazon and Meta, is poised to grow by 14.1% to a total of $741.4bn – over two thirds (68.8%) of all ad spend.
Social media is the largest individual sector within pure play internet – and the largest advertising medium of all by extension – with a total of $252.7bn this year equivalent to 23.5% of the global ad market. Prospects for the social market have been revised upwards this year to +19.3%, owing mostly to stronger-than expected results for Facebook, Instagram and TikTok over the first nine months of the year.
Google rules?
One in five dollars (22.1%) spent on advertising outside of China is paid to Google for its search services. Further, at an expected $197.7bn in 2024 (+13.0% year-on-year), Google alone accounts for 90.1% of all search advertising (excluding China). These commanding shares are similar in the US, leading the Department of Justice (DOJ) to rule last week that Google has an effective monopoly on the search market.
The court believes that Google also uses its search dominance to inflate the cost per click (up by approximately 7.5% this year) and maintain superior targeting, effectively blocking competitors from offering viable alternatives.
Outcomes from the ruling range from Google ceasing payments to handset manufactures and others for default preference – at a cost of approximately $30bn per annum – to the selling off of its Chrome business to a third party.
One potential suitor – Bing – still struggles with adoption and advertiser investment despite Microsoft’s $100bn investment, accounting for just 5.9% of search spend outside of China. Bing’s ad revenues are expected to be up just 5.1% this year – compared to a rise of 11.9% for total search and 13.0% for Google – to a total of $12.9bn.
Apple opportunity?
Apple already makes $5.1bn from search ads, mostly via its app store, per Omdia Advertising Intelligence estimates, and could create its own search engine given its financial and distribution resources. The device manufacturer may hesitate to proceed, however, due to the high costs associated with maintaining a search business aside a general strategic misalignment. A leftfield entrant – perhaps Elon Musk’s X on the lookout for new revenue streams after losing $5.9bn in ad revenue since its 2022 takeover – may materialise, but on the whole natural successors to Google remain unclear.
With the ongoing uncertainty around the practicalities of the DOJ ruling, and the probability that Google will appeal it vigorously in the coming months, WARC is maintaining its growth forecast of +9.0% next year and +7.0% in 2026 for the company while the situation develops, leaving a potential $231bn ad business and $32.9bn of growth in the balance over the next two years.
Linear TV surprise
While the headline growth rate is mostly being driven by online media, a good year for TV has also made a notable contribution. Linear TV spend is expected to end the year 1.9% higher, at $153.6bn, following two years of decline. TV has been boosted by political advertising – particularly in the US – during the fourth quarter and both the Paris Olympics and the Euro 2024 football tournament in the third. Linear TV now accounts for just 14.3% of global advertising spend, however, down from a peak of 41.3% in 2013.
James McDonald, Director of Data, Intelligence and Forecasting, WARC, and author of the research says: “Our latest forecast anticipates $104bn in incremental advertising spend worldwide this year, the largest rise in history if the post-pandemic recovery year of 2021 were discounted.
“Whether this boom will sustain remains unclear, however, as 2025 presents a sliding doors moment due to heightened regulatory pressures on Google and TikTok – together a quarter of the ad market outside of China. This, alongside an increasingly challenging geopolitical climate, may spell uncertain times ahead for the businesses that rely on advertising trade.
