Apple’s latest software update continues its drive to limit the data that can be collected about iPhone users as they browse the internet. Prior changes have had an effect on ad prices for publishers, and on advertiser results

The new changes target cornerstones of profiling and targeting: IP and email addresses. The impact will be gradual, but could be profound if takeup is high

The lesson for publishers is that no technical implementation of targeted advertising is safe. Layering third-party data on top of anonymous audiences is not a future-proof business model

Amazon has been criticised by commentators, governments and sellers for giving its own products an unfair advantage on its online storefront, which millions of sellers depend on for discovery

This line of attack misses the point of Amazon’s business, which is to operate marketplaces and extract profits from suppliers through fees and services. This model raises its own questions about competition and fair trading, but self-preferencing is not core

Amazon's strategy needs both buyers and sellers, but it needs to focus on the experience for customers as the foundation of its market power

Apple is bringing in privacy changes on iOS that could hurt ad-funded apps. 

Responding to platforms’ legitimate push for user privacy is a trial for regulators in the midst of building new online antitrust regimes. 

Antitrust rulings are chipping away at the App Store’s stringent terms of use, but reforms will keep it at the centre of the iOS universe. 

Facebook emerged from 2020 reporting record revenue growth of 22% over the year, built on its huge volume of usage, its simple buying tools and its trove of first-party data.

Facebook’s ability to match third-party data for targeting and attribution is also central to its success. However, Apple and Google are restricting data-matching tools like third-party cookies and mobile IDs, and Facebook is moving to minimise the damage.

Facebook is trying to turn its sites into storefronts by launching ‘Facebook Shops’. It is also taking public stands on the use of data for advertising, and on the need for brand-building in marketing plans. These are conversations all advertisers and media owners should be engaged with.

The Consumer Electronics Show (CES) this year was held virtually, with announcements revolving almost exclusively around the pandemic and addressing changing consumer needs. The evolving use of tech at home was a particular focus for brands as consumers are now demanding more of their homes than ever before.

Following a record 2020, ecommerce was a topic that garnered a lot of attention, with retailers emphasising the importance of a consumer centric 'digital first' strategy, accepting the fact that ecommerce is going to be bigger than it ever has been.

Amid increased tech use at home, moves to ban third-party cookies and impending regulatory changes to data collection in the US, the conversation around data and privacy was more prominent than ever before. First-party data is going to be more valuable, even if tracking restrictions limit what can be done with that data.

Spotify is investing heavily in podcasting through acquisitions, original content and product innovation

It is under pressure to reduce dependence on record labels, whose power makes generating large profit margins difficult. Podcasts promise a non-music content genre where Spotify can capture more value

Secondary benefits abound: Spotify can take an active and lucrative role in modernising online audio advertising, it can solve the podcast discovery problem, and engagement across more forms of audio will improve retention

After the most challenging period in its history since 2012, Facebook has been able to stabilise its fundamental metrics and announce a major product overhaul

Despite talk of a business model pivot, Facebook’s focus remains on advertising, whose growth will remain concentrated in developed markets

News publishers wishing to stay relevant on the upgraded product set need to target exclusive layers of social interaction, with groups particularly important

New car registrations will be down 6.3% (2.4m) in 2018, another year of decline from the 2016 peak of 2.7m, impacted by the soft consumer confidence in big-ticket purchases, with some spin down to used car sales

Auto Trader, despite the car industry’s downturn, has experienced only marginal pain thanks to the strategic focus on revenue diversification – principally into new cars, dealer auctions and enhanced subscription-based services for dealers

Our forecasts for media expenditure on cars in 2018 and 2019 are essentially flat. Auto Trader’s positioning offers insulation in a downturn, and we expect they will gain share in marketing spend, though not necessarily in terms of total consumer or industry expenditure

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
