This week, the digital economy delivered a tale of two trajectories: advertising and streaming surged ahead, while regulators intensified their crackdown on platform power. In today’s MadTech Daily, we cover ChatGPT and Roblox facing the EU’s toughest platform rules, Elon Musk settling X’s ad group lawsuit, and Meta’s shares falling amid investor concerns over rising AI spending.

Google found itself at the centre of Europe’s regulatory spotlight after the European Commission imposed €890m in fines for two separate Digital Markets Act breaches. Brussels said Google unfairly favoured its own shopping, travel, hotel and sports services in Search, while also restricting app developers from steering users toward cheaper payment options outside Google Play. 

The scrutiny of market dominance was not limited to Europe. In China, regulators hit Trip.com with a 5.2bn yuan ($765m) penalty for alleged monopolistic conduct, arguing the travel giant abused its dominant position across its online travel platforms. 

While regulators tightened the screws, the advertising market painted a much brighter picture. UK ad spend jumped 9.3% year-on-year to £11.7bn in Q1 2026, with digital channels leading the charge. Search remained the largest category, while social media, retail media, digital out-of-home and addressable TV all posted double-digit growth, signalling continued confidence in data-driven and measurable media.

That momentum was also reflected in the agency world. Havas reported solid first-half results, delivering 2.5% organic net revenue growth and a stronger profit margin, suggesting that large holding groups are continuing to benefit from sustained client investment in media, technology and AI-enabled services.

Streaming, meanwhile, crossed a symbolic threshold. According to Ofcom’s latest Media Nations report, Netflix has overtaken the BBC as the UK public’s first-choice viewing destination, with 26% of respondents choosing Netflix compared with 25% for the BBC. 

Audio was another area of notable movement. Amazon Ads struck a programmatic partnership with Octave, bringing News UK’s portfolio of podcasts and digital audio inventory directly into Amazon DSP and expanding advertisers’ access to more than 15 million connected listeners. At the same time, a broad coalition of podcast platforms, creators, agencies and brands released a new whitepaper calling for standardised podcast measurement and ad attribution, reflecting the industry’s push for more consistent metrics as podcasting becomes increasingly video-first and platform-agnostic.
