The commercial non-PSB sector saw strong growth in share of total TV viewing of close to 40% as the multichannel TV homes universe doubled in the 10 years between the launch of Freeview in October 2002 and completion of digital switchover in October 2012, and even higher 50% growth in SOCI (share of commercial impact) thanks to the higher commercial airtime quotas of the non-main PSB channels

Even during the growth years, non-PSB channels that were present in 2003 felt a squeeze on viewing share and suffered losses as result of numerous channel launches that added to the long tail (Squeeze 1), and strong growth in the PSB families (Squeeze 2), which saw the total PSB share among the Top 25 channels in multichannel TV homes rise from less than 80% to over 90% between January 2003 and January 2014

Today, both the PSB and non- PSB commercial channel groups face the challenge of internet connectivity and increasing population of portable screens (Squeeze 3), and they are experiencing similar rates of decline. Yet, even if overall trends look the same, non-PSB viewing trends show significant variation by channel group and genre, to be explored further in Part 2

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

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.

2013 has seen yet another year of strong growth in consumer adoption of mobile devices and screens adding to the challenges facing traditional media. Press and radio have long been affected, but television is now starting to feel the heat

BT and Sky’s contest for premium pay-TV sports rights has intensified. August saw the launch of BT Sport, while BT’s acquisition of the European football rights in November was a clear statement of intent, spending half of Channel 4’s total programming budget on approx. 200 hours of content

The UK has seen buoyant advertising growth of around 4% in 2013, with similar growth expected in 2014, in the context of the strongest economic recovery in Europe

Scotland’s SNP-led Government has published its White Paper setting out its assumptions for independence, including on broadcasting and telecommunications, where spectrum management will be assumed by the new Government, implying a discontinuity in existing UK-wide 3G and 4G licenses attributed by Ofcom.

The SNP promises no change in the broadcasting environment except for the creation of a Scottish Broadcasting Service (SBS), which would occupy the BBC’s position today. Channel 3, 4 and 5 licensees will be able to continue to broadcast without discontinuity, although free access to spectrum was not promised, which BSkyB of course doesn’t require.

The big ask is BBC One and BBC Two on free-to-air terms, implying a subsidy of £270 million to Scotland. This seems very unlikely to be agreed by the rest of the UK (rUK), since BBC Worldwide offers only commercial terms to other countries. However, the BBC will not comment on this assumption, so the Scots will only learn of the facts after the referendum.

For the BBC’s DG Tony Hall, “Where next?” primarily means more digital, expanding its iPlayer internet TV and radio application and offering greater personalisation

These moves form part of a wider strategy to ensure BBC services and programming can be delivered seamlessly across devices in the most relevant form, whilst maintaining access and appeal to all age groups

Reaction from commercial rivals and commentators has been muted, likely saving powder for the soon-to-begin battle over the BBC’s scope and funding from 2017, when the current Royal Charter expires

Apple’s two new iPhones both secure its grip on the high end (for now) and extend a cautious toe into (slightly) cheaper waters. They will not deliver a step change in global sales growth, but should deliver solid performance

9m unit sales at launch are impressive, but 200m updates to iOS 7 (double last year’s figure) point to the continuing strength of Apple’s ecosystem and its ability to deploy innovative new features

We continue to believe there is room in Apple’s portfolio for a $350-$450 phone without weakening Apple’s quality of experience or brand positioning, but this is clearly now off the agenda for another year

A cheaper iPhone has been discussed almost since the original launch in 2007, but we believe costs have fallen and the market developed to the point that it now makes sense for Apple to offer a $200-$300 (unsubsidised) model.

We see a positive but fairly small financial impact on Apple. The key benefit would be defensive: by extending the ecosystem and preserving iOS as developers’ first choice, Apple would secure the whole portfolio.

We believe a well-executed and distributed $200-$300 iPhone would sell double-digit millions of units – a significant challenge to Android OEMs and Google. However, the US market’s pricing structure might limit the impact there.

By the end of 2013 there will be more iOS and Android devices in use than PCs. Google is using Plus and Android to reposition itself to take advantage of this, extending its reach and capturing far more behavioural data

We believe a helpful way to look at Google is as a vast machine learning project: mobile will feed the machine with far more data, making the barriers to entry in search and adjacent fields even higher

For Google, Apple’s iOS is primarily another place to get reach: we see limited existential conflict between the two. However, mobile use models remain in flux, with apps and mobile social challenging Google’s grip on data collection
