With c.22m accounts across 44m devices, Roku has a US footprint which exceeds the largest pay-TV platforms

Limited competitive advantages highlight the scale of this achievement, but also leave the pioneering firm vulnerable to activities from bigger, wealthier rivals Apple, Amazon, and Google as well as pay-TV providers

The odds are stacked against Roku, but continuing the innovation in production and product that built its lead may secure future success

The Information Commissioner’s Office reported on the UK online advertising sector, finding common industry practices unlawful under a strict interpretation of the GDPR and UK privacy law

The ICO focused on problems around transparency, consent and data sharing in the Real-Time-Bidding ecosystem, which comprises 16% of UK online ad spend, but most of publisher online ad revenue. The ICO is giving the industry six months to shape up, with the next steps still unclear

The Competition and Markets Authority has had under consideration an investigation into the entire online advertising sector, but is hampered by Brexit-related considerations

European mobile service revenue growth slipped again to -2.0%; its worst performance in four years

Regulation limiting intra-EU call prices could hit hard next quarter – with the UK likely to be hardest hit by up to 6% of revenues and 20% of EBITDA

Excluding the EU-call impact, we see greatest scope for improving trends in Italy and France thanks to easier comps and diminishing competitive intensity

After a period of significant outperformance, O2’s Q1 results reverted to sector average revenue growth with ARPU down by 3% and all of the growth coming from ‘other’ revenues

Regulation limiting out-of-bundle spending has been a significant drag which will continue to worsen

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

Sky made a surprisingly weak start to 2019, with revenue growth decelerating to 1.9% (the first time below 4% since the European businesses merged in 2015), due to weaker ARPU trends.

However, Sky expects improvement to follow, blaming one-off factors in the quarter. The ARPU weakness drove EBITDA down 11.3%, but this should bounce back across the rest of 2019 as football rights costs turn from a drag to a positive.

Comcast highlighted collaborations with Sky across tech, advertising, content distribution and even news, stating it is on track to achieve the anticipated $500 million in annual synergies over the next couple of years.

Out of Home (OOH) is bucking the trend in UK traditional media and continues to grow, driven by the digitisation of inventory as the paper estate recedes

Digital OOH now accounts for 50% of total OOH ad spend. Soon digitisation will slow, as much OOH inventory cannot be converted from posters to digital screens; sustained growth will require a different form of change

The industry is amidst structural shift – driven by consolidation and automation – which could be wholly positive, but a lack of cooperation between major players risks stifling innovation and the medium’s growth

Google is building its own game studios – to win over others it must overcome a troubled history in gaming, mitigating risks to developer business models and creative integrity

Games are much more technically demanding to stream than video, presenting an advantage to Google, Microsoft and Amazon – and a boost to telecoms network demand, welcomed by operators

European mobile service revenue growth dropped to -1.3% – its lowest level in three years – particularly disappointing as growth should be bouncing back post-EU roaming tariff cuts

Having enjoyed relatively favourable dynamics in 2018, the UK and Germany are facing marked changes in momentum from here

Regulation limiting intra-EU call prices could hit hard – up to 6% of revenues and 20% of EBITDA in the UK, although other EU countries may be less exposed due to lower tariffs currently

UK online advertising spend continued its double-digit growth in 2018, up 11% to reach nearly £13bn in annual spend or 58% of the total advertising market, but a no-deal consumer downturn could nearly stop growth this year

Google, Facebook, Amazon, professional services firms and the largest marketing cloud companies are the biggest winners, while content media, media agencies and independent advertising technology firms languish 

Self-regulation has improved as pressure mounts on advertising technology firms, but interventions by both privacy and competition authorities are now inevitable
