The US Department of Justice antitrust case against Google alleges an illegal monopoly in search and search advertising in their home and largest market.

The lawsuit targets Google's control of the Android mobile operating system and exclusive revenue share agreement with Apple, which the EU prohibited in 2018, a decision that Google has appealed.

Alongside antitrust enforcement, legislative initiatives in the EU and UK will create an ex ante antitrust framework for relations between “gatekeeper” platforms and their users and customers, which the US Congress has yet to emulate.

ByteDance is rushing to sell a 20% stake in TikTok Global to Oracle and Walmart at an enterprise value of $60 billion. TikTok otherwise faces a ban in the US on 12 November, subject to legal challenges.

The sale hinges on ByteDance obtaining approval from China to export TikTok’s core technologies. China updated its export control rules to include algorithms (and AI), entrenching a tech cold war with the West.

TikTok has confounded regulatory woes in India and the US, and renewed competition from US tech, to post dizzying user growth in every major internet region where it is available, casting off its image as a niche youth product and entering the mainstream.

Apple’s developer conference coincided with a period of unprecedented tension with its developer community, parts of which are chafing under Apple’s rules for the iPhone App Store.

These rules let Apple extract a large portion of the value of the App Store. This revenue is more important than ever to Apple’s growth story, so it has been applying its rules more strictly.

Apple is constrained here by the need to deliver the best product possible to its users, and by the possibility of regulatory intervention.

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

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. 

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
