TalkTalk hit the bottom end of its (revised) 2018/19 EBITDA guidance, an achievement given fierce price competition and the margin-dilutive effect of high speed upgrades

This is however helped by one-off Openreach price cuts, and price rises for ancillary products (voice calls and pay-TV) and out-of-contract customers that look hard to sustain

Subscriber growth slowed dramatically in Q4, and continuing this more measured approach could help the company counter multiple market pressures, and perhaps even lead to a détente in the current price wars

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.

The economic model of TV production relies upon a vibrant market for back catalogue content; programming that has traditionally driven the desirability of many linear channels and slots

New release strategies, along with the hyper-concentrated viewing encouraged by video-on-demand and the round-the-clock availability of shows calls the longevity of the value of content into question

Our analysis suggests that programmes that previously would be leisurely distributed through broadcast could now feasibly be “worn out” more quickly. This could have ramifications for the whole sector, with more content investment required “upfront” and new financial and distribution models required

Google’s Stadia promises the most credible game streaming service yet, but building a subscription bundle of top titles would require an all-out bet in the sector

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

Market revenue growth accelerated to 3% in Q4, but it might never reach this level again, being helped by a never-to-be-repeated BT overlapping price rise

With price rises becoming more challenging in general, and superfast pricing under pressure in particular, maintaining/increasing ARPUs is becoming more difficult despite superfast volumes surging

Openreach’s ultrafast roll-out has accelerated, challenging Virgin Media and bringing the prospect of further price premia, but perhaps too late to be of significant benefit in 2019

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

After strong underlying 2018 results, the more subdued outlook for 2019 is an important shift, driven by regulatory pressure on mobile, higher programming costs, one-offs and softening demand

Lightning is continuing to drive market share gains in new build areas, and should provide a 2ppt tailwind to revenue growth in 2019, but enhanced visibility on the economics of rollout suggests that its conservative approach is a wise one

In existing build areas, Virgin Media is facing-off pricing pressure from TalkTalk on high speed, and potentially from BT on even higher ultrafast speeds, with it moderating pricing and launching a market-beating 500Mbps product in Spring 2019 in response

Launched to the world in September 2017, TikTok is the first Chinese app to pose a serious threat to Western social media companies as it attracts hundreds of millions of Generation Z users around the globe

Privately-owned parent company Bytedance earned $7 billion in online advertising revenues in 2018 and is valued at $75 billion, placing it ahead of Uber as the world’s most valuable internet start-up, with an IPO likely this year

Bytedance’s goal of earning half its revenue outside China by 2022 is far from certain. In order to hit the target, TikTok will need to attain super scale with best-in-class revenue per user, an unlikely combination

Consumers have more shopping options than ever, forcing businesses to expand how and when they offer services. Online giants Amazon and Alibaba are adding physical retail to extend their routes to market

Omnichannel provides consumers an enhanced, seamless brand experience from research and discovery to purchase, delivery and after-sales, and allows businesses to react to changing consumer preferences more flexibly

Next is an omnichannel success story, introducing 48-hour home delivery in 1988 and online sales in 1999. Its market-leading fashion ecommerce business offers lessons on the future of retail

Across the EU4, pay-TV is proving resilient in the face of fast growing Netflix (with Amazon trailing), confirming the catalysts of cord-cutting in the US are not present on this side of the Atlantic. Domestic SVOD has little traction so far.

France's pay-TV market seems likely to see consolidation. Meanwhile, Germany's OTT sector is ebullient, with incumbents bringing an array of new or enhanced offers to market.

Italy has been left with a sole major pay-TV platform—Sky—following Mediaset's withdrawal, while Spain's providers, by and large, are enjoying continued growth in subscriptions driven by converged bundles and discounts.
