Watching traditional linear TV has shown a sharp decline among younger adults over the last two to three years and the question is how far it has to go before bottoming out. This report explores the causes and presents our forecasts up to 2020

We see the main causes of this as the growth of online connectivity associated with the proliferation of screens via smartphones and tablets, the increasing functionality of these other screens, the increasing population of connected TV sets and the growing volume of long and short form content that can be accessed over the internet

Examination of current “connectivity” trends suggests that 2013 will prove the peak year of decline. Thereafter we expect trends to stabilise over the next three or four years without fundamental change to the linear TV landscape

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.

Ofcom has been instructed by the UK government to charge the mobile operators ‘full market value’ for the 2G spectrum they have been using for many years, despite there being no liquid market for the spectrum

Ofcom’s general approach to such an imponderable question is eminently sensible, but we disagree with the detail of their methodology on three key aspects, which makes the current proposed charges over three times too high in our view, effectively charging the industry a one-off tax of £4.5bn

The elevated fee levels are (perhaps) still affordable on their own, but coupled with other recent regulatory decisions the UK is in danger of being seen as a hostile regulatory environment, with negative consequences for future investment levels

The stress on 21st Century Fox’s Italian pay-TV platform is easing as the worst recession of any G8 country is expected to end in 2014, and competitive pressure from Mediaset is weakening

Sky is sticking to a long term strategy, investing in the (unrivalled) quality of its offering and sustaining high recruitment costs. The subscriber base seems to have levelled off, revenues are stable, but profits have collapsed. Management plans cost cuts to raise profitability by 2016

The upcoming auction for the 2015-18 football rights could see Sky gaining more exclusivity at a higher cost, which it would have to recoup mostly by rising prices. The key potential upside resides in an Italian economic upturn – which is only conceivable in a few years

Richard Desmond’s appointment of Barclays to explore the sale of the Channel 5 Group in 2013 has fuelled speculation over prospective purchasers should Northern & Shell be intent on selling this asset

The reported target of at least £700 million, seven times the £103.5 million paid by Northern & Shell to RTL three years ago, reflects a strong performance in 2013, but needs to be against several distinctive factors, including Channel 5’s near total reliance on advertising and the cross-promotional benefits it gains from the Northern & Shell print publications

Regulatory and strategic considerations suggest that neither ITV nor the pay-TV platform operators, Sky and BT, are likely to emerge as serious bidders and that an overseas group from the US is the most likely outcome if a sale is to take place

We have recently completed our December survey of UK mobile users, which shows increased purchase intentions for handsets in general and camera phones in particular.  We summarise the results in this note, which are good news for handset manufacturers, but more mixed for the operators.

In January the UK Competition Commission (CC) is expected to issue its report on the pricing of mobile termination rates, an issue that was referred to it by Oftel after the UK operators rejected Oftel's initial decision. In this note we speculate on the likely contents of the report, and the impact on the UK mobile industry.

This report provides our forecasts for the growth rate of digital television homes in Europe over the next three years. We split countries into four groups and predict how the numbers of households with access to digital delivery of television will change in each group. The growth in satellite delivery has slowed considerably during late 2001 and 2002. The digitalisation of cable has stalled almost everywhere. So the only major uncertainty lies in the growth of digital terrestrial homes. This year has seen the failure of two of the four existing services, but the rebirth of the UK operator, in the form of the BBC's Freeview, may herald a more successful era. First indications are that Freeview is doing well. In other countries, however, the obstacles to the growth of a free-to-air service are more significant than in the UK and we do not believe that DTT will experience rapid growth in many other countries, despite the plethora of launches planned in the next few years.

In the next few days, NTL expects to emerge from Chapter 11, relieved of $11 billion of debt. While the long negotiations over financial restructuring have been in progress, NTL management has been conducting a huge cost reduction exercise largely out of the public eye.
