TikTok has reached a billion users worldwide just four years after its global launch, much quicker than social media rivals, though its ban in India is a drag on growth.

TikTok’s popularity with under-25s has contributed to a hollowing-out of Meta’s active userbase. During the pandemic, TikTok also expanded its reach among older demographics, cementing its position within the mainstream and posing a further threat to Meta. 

TikTok could earn twice as much revenue as Snap in 2022, making it the first app to break out of the mid-league in years, with a huge runway for growth backed up by ByteDance’s remarkable success in China. 

Alphabet's stunning growth reflects a shift online that has outlasted pandemic restrictions. Google search is at the heart of online commercial activity

YouTube's slower growth is not yet cause for concern: it is still the biggest website in the world, with growth potential through subscriptions and transactable ads, as well as more brand spend

Alphabet might struggle to balance privacy concerns in the context of the online advertising ecosystem. The future of personalisation in ads is uncertain as Alphabet cancels one of its cookie-replacement technologies

Recorded music revenues in Japan are stuck in decline as physical sales sag, although 2017 marks the first year when streaming gained a foothold with 8 million subscribers. 

J-pop fans spend on 'experiences' with their idols including events, merchandise, CDs and DVDs, which streaming cannot replicate. Top native LINE MUSIC offers integration with a popular messaging app and bundling with mobile. 

Serving international repertoire, Apple Music claims more subscribers than Spotify in Japan, which is more localised, and has most users on the free tier. Amazon Prime Music is a looming constraint on the adoption of subscriptions. 

Rigour and consistency in AV ad metrics is proving elusive. A 10-second ad on YouTube, ITV1, All4, MailOnline, Sky AdSmart or Facebook is measured in as many different ways, often indifferently. It is tricky, costly or impossible for agencies/advertisers to comprehend the overall picture.

By 2020 JIC-based BVOD ad impressions should be available from BARB all being well, giving BVOD a clear advantage over other premium online video measurement.

Google/YouTube seems to be ‘getting’ JIC co-operation now and has begun to galvanise video ad measurement, but forceful advertiser intervention is needed to extend and improve standards. Otherwise, advertisers are simply funding a JIC-free jamboree, and they (with content media) will lose the most.

Online advertising became the majority of all UK ad spend last year, in step with China but ahead of all other major markets. 

Direct response has further increased its share to 54% of UK ad spend, fuelled by the self-serve platforms of Google, Facebook and Amazon, while content media nets just 11% of the online advertising pot.

We estimate that all online-delivered channels - including "pure play" online properties, broadcaster VOD, digital out-of-home and online radio - could account for well over 60% of UK ad spend by 2020, but only with improved commitment to industry governance. 

Spotify is now the world’s first publicly listed on-demand music streaming service. Its global footprint generated €4 billion in 2017 from over 70 million paying subscribers and 90 million ad-funded users across 65 countries

As it expands, the service is steadily but surely moving ever closer to profitability, with a 2019 operating profit a very real prospect

So far and for the near future, Spotify’s global pre-eminence versus competition from Apple, Amazon and Google proves remarkably resilient. Plans to build upon its differentiating features will become ever more decisive as the tech titans will continue to wield their resources and ecosystems against the comparatively undiversified company

The market for addressable TV looks constrained despite its benefits, with Sky AdSmart taking less than 2% of overall TV ad revenues. Meanwhile, online video revenues for Google, Facebook and others have surged dramatically

Agencies are seemingly enraptured by online video – a highly profitable medium to buy – despite concerns about a lack of effectiveness, safety and transparency 

For broadcasters to compete, better radical collaborative action is needed, including industry-wide adoption of AdSmart, and overhauling the trading agreements which hinder its take-up

We forecast UK display adspend to grow by 3.1% in 2018 (<1% in nominal terms), with TV roughly steady, newspaper decline slowing and digital growth slowing a little

Households are facing an income squeeze and the ability of debt and credit to carry them over is reaching its sensible limit. Brexit-related uncertainties remain the single strongest drag on business investment, dampening ad spend

TV spend is the £5bn question. While live viewing continues to decline, TV delivers against different marketing objectives from precisely targeted online inventory, and rapid broadcaster VOD growth will help hold TV spend steady
