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. 

Apple’s record December quarter closed off a huge year for the company, with little sign that supply chain problems affected the core iPhone business. Services, meanwhile, remain strong, and the company’s status as the world’s biggest subscription provider positions the business for a metaverse future.

Apple’s ability to control platforms like the App Store is under regulatory pressure. Apple is ceding ground where it can, while keeping fees high for the mobile gaming cash cow.

China has returned as a meaningful contributor to growth. US sanctions have toppled China’s Huawei, to the benefit of the American firm.

With elections in the UK in December, and in the US in 2020, online political advertising is receiving intense scrutiny. Google has announced limits on targeting, while Twitter has banned politicians from buying ads

Facebook is the big player in online political ads, and it continues to allow targeted political ads, and to carve them out as exempt from fact-checking

Facebook wants to keep Republicans on side and surf the revenue opportunity, but pressure will increase with US elections, and we expect Facebook to bring in restrictions

Apple’s iPhone launch event was relatively light on iPhone, which shared the stage with games, TV, Watch, iPad and retail announcements

This reflects Apple’s developing priorities: as iPhone sales soften, it needs to find new ways to extract value from the wealthy user base it has spent a decade nurturing

Apple has embraced this new strategy, offering a range of cheaper points of entry into its ecosystem, making the lost profits back on accessories or content subscriptions

Google’s advertising business has begun losing market share in the US, with competition from Amazon, Facebook and Microsoft intensifying in search and display

In response, the company is redoubling efforts to reshape its apps, services, and the entire web for more efficient monetisation, spelling uncertainty for partners and users

The adaptability and complexity of Google’s services reduce business risk from targeted regulatory measures, but increase the pressure for a radical intervention

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

Apple is strengthening its household model by doubling down on family-friendly content subscriptions and payments

The model is reliant on hard bargains with mainly US partners, which risks sacrificing potential scale for a short-term boost in margin dollars

The new services offer glimpses of novel concepts, but stop short of taking risks to truly differentiate—a problem in TV, where Apple’s distribution advantage is slimmer than Oprah would have it

Amazon’s recent deals with Apple in TV, music and device sales mark a turning point after a decade of frosty relations

The context for this involves shifting priorities at both firms, growing pressure on Apple’s iPhone business, and rivals in common — first and foremost Google, but also the likes of Netflix and Spotify

The uneasy alliance helps both companies consolidate their strengths in the platform competition over media and the connected home — but trouble already brews

Google has beaten Facebook in mobile revenue growth, and competes successfully in retail search with Amazon

Intelligent user interfaces based on machine learning have become a core competitive strength, with social and messaging the main remaining weak points

Rising political pressure due to Google’s growing scale and influence is now a bigger concern than commercial risk, as the threat of regulatory intervention limits strategic options in partnerships, M&A and integration

Even though Facebook is not a producer of news, 6.5 million UK internet users claim to mainly source their news from the platform. Posts and shares by friends in the user's network, in the context of Facebook's algorithm, determine the order of stories in the personalised News Feed, removing the control of the news agenda that publishers have for their websites

Premium publishers operating a paywall (The Times, The Financial Times) have a lower key approach to Facebook than publishers generating advertising revenue from referral traffic to their websites or from on-platform consumption of Instant Articles. The latter will seek to stimulate social media engagement, optimising stories through attention-grabbing headlines, and installing Facebook’s share and like buttons on their websites

Case studies of the news stories that were prominent on Facebook (measured by likes, comments and shares) in the periods leading up to the Brexit Referendum and General Election 2017 votes respectively demonstrate that newspaper brands (the Express for Brexit, and The Guardian for the General Election) achieved the highest reach on Facebook during these periods, despite being ranked below other news brands (BBC in particular) in terms of traffic to their websites
