Amazon has entered the increasingly crowded digital entertainment TV device marketplace, one which could be strategically more important for the ecommerce giant than tech rivals Apple and Google

The frictionless integration of entertainment and ecommerce on TV represents a bigger consumer milestone than competitor services are offering, and Amazon’s brand has huge appeal, though at present it has less market traction for streaming than it does for other products

Content owners and broadcasters remain the real TV gatekeepers, with integration of TV and digital a service-level pipe dream for now, and so Amazon will likely have to accept being one of many, rather than the runaway winner as it is in books

European mobile service revenue growth again disappointed in Q4, dropping slightly from -8.9% to -9.1%, with underlying revenue growth dropping a little further from -6.0% to -6.3%, again reaching a record low

There had been hopes that improved GDP growth would drive a volume rebound, that price declines would start to annualise out, and that declining out-of-bundle usage would wane in its impact as this usage declined. In the event, ongoing price competition from smaller operators, MVNOs and quad play offerings, combined with surging use of OTT communications platforms, have dominated trends

In the medium term, the development of 4G and Vodafone’s Project Spring may bring some much needed network differentiation back to the market, allowing pricing power to return to the larger operators. However, it will be 2015-2016 before these factors come into play: in the short term, the main source of optimism is consolidation

In 2013 Sky focused on recruiting ‘quality’ subscribers: net additions fell but ARPU growth accelerated and most new customers have signed up to two-year contracts, which will lead to a reduction in churn

Now Sky is moving its focus back to subscriber growth. It aims at 400-450,000 net adds this year, including the migration of wholesale DTAG customers – a target we find realistic. The €70-90 million EBITDA guidance may be conservative

Without any direct competitor, Sky is rightly enhancing its all-in-one premium appeal. This supports ARPU growth and increases its distinctiveness compared to other providers, including the expected Netflix launch in Germany

Explosive growth in take-up of smartphones and tablets means that the effective size of the internet will increase by several multiples within the next few years. This transformation in scale comes with a major change in character and operating dynamics, creating new opportunities and revenue streams.

Twitter is unique amongst social apps: it gives new users a blank canvas in which they can (and must) create their own social network reflecting their own interests, hence building an ‘Interest Graph’, but onboarding new users remains a challenge.

Revenue at Twitter is now on a $600 million annual run-rate, scaling rapidly since the introduction of ‘native ads’, and seems set for further growth: the key question is whether it can achieve breakout user growth and mass market scale.

The Charter Review of the BBC officially opened with the Culture, Media and Sport Committee’s inquiry into the Future of the BBC asking the question “What should the BBC be for and what should be the purpose of public service broadcasting?” The only obvious answer is that the BBC and public service broadcasting should be for the people of Britain, and the BBC rates highly on different measures of public and audience engagement. The BBC plays an irreplaceable role in the supply of PSB programming that UK audiences appreciate, most importantly news, where the BBC accounts for 70% of TV news time and for 22% of online news time in 2013.
