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.

Non-subscribers can download this report in full - alongside all our other coverage of the BBC during the Charter Review process - from the 'BBC Charter Review' page of our site.

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

15 million UK adults regularly (at least once a month) accessed the Internet from home in Q3 2001, the same as in Q2 2001. This stagnation is due to mainly seasonal factors and we expect growth of the home Internet population to be renewed in the autumn and winter.

Our lower forecasts are derived from an analysis of the numbers of households and small businesses that are apparently prepared to buy ADSL at current price levels, but also driven by concerns about this particular product. Users will have to acquire new email addresses and pay for a new email service. We do not think the product will work in networked multi-PC homes or offer ISDN users a real alternative. We see tremendous confusion in the marketplace from two competing BT Broadband offerings from BT Retail and BTopenworld.

This report contains our analysis of the French TV market. France, like the UK, is a difficult market for pay-TV and, recently, for some analogue terrestrial channels as well. We look at the analogies and differences between the two countries. In both places, excess competition and declining advertising revenues are beginning to create cracks in the noble edifices of the major TV groups. As in the UK, we conclude that analogue commercial TV may be less affected by digitalisation and pay-TV than most analysts expect.

We conclude that the economics of both free and premium digital terrestrial television are so unattractive that no rational bidder would enter the race for the licence. Likely advertising revenue on free channels will barely cover the transmission costs, while pay services will be crippled by astronomical subscriber management costs and low, or negative, margins on channels provided by BSkyB.

In this note we summarise the available evidence on trends in ARPU among European mobile operators. We demonstrate the increasing trend towards stable or increasing revenue per subscriber in key markets. The end to the long downward trend in voice ARPU is clearly in sight. This new stability is derived from increasingly firm call charges and slow growth in minutes of use. Local competitive conditions may disrupt this pattern in individual countries – and we demonstrate the countervailing trend in Finland – but, overall, the pattern is clear and will probably become more so in the next few months.

More important, perhaps, the current economics look acceptable both for BT's Wholesale and Openworld divisions - this note includes some detailed financial analysis. But even at the lower price levels, we remain unconvinced whether subscriber numbers will grow as rapidly as BT predicts. (BT is now saying that ADSL subscribers will be more numerous in 2005 than unmetered customers are today!)

The regional newspaper business in the UK is a mature industry with improved operating management and a small number of powerful players.

The bulk of the report examines in detail the structural forces determining the growth of ISPs in Wanadoo's main territories - France and the UK. It looks at the scope for raising revenues through broadband growth, increased advertising or e-commerce revenues. We look at market shares, and the factors that drive growth and decline.
