Google’s income in Q3 was hit by fx headwinds and a rise in traffic acquisition costs (TAC) for its ad business as well as by higher than expected losses at Motorola

Headline growth in gross advertising revenue continued to slide, primarily due to the effect of the strong dollar; of more concern, rising TAC cut gross margin by 3 ppts

Mobile now accounts for the majority of growth in ad revenue, which should improve as mobile ad yields rise, though net margin could decline if Google has to pay out a greater share to partners such as Apple

The third of our four reports on specialist advertising focuses on the automotive sector and AutoTrader's role at the heart of the dealer ecosystem

The used car market has been remarkably resilient in recent years, but as with many classified categories the core trend in digital is diversification to a suite of services from a core listings model

AutoTrader's owners Apax Partners and Guardian Media Group will of course be considering their options in terms of an exit from their investment

The second of our four reports on specialist advertising focuses on the property sector, and specifically assesses the implications for Rightmove and the sector generally of the merger of Zoopla with DMGT's property portfolio, which includes Find a Property and Prime Location The merger creates a market duopoly that will put print media under further pressure, though Estate Agents remain attracted to the lead-generation and attractive branding benefits of print distribution and layout Meanwhile, the sector has rebased in scale: while house prices are in aggregate very stable, transaction volumes are still only a little more than half the market peak in 2007

Since the onset of the recession in 2008-09, the revenues and profitability of the recruiters, auto dealers and estate agents which purchase print and online advertising media have been impaired by lower transaction volumes, putting pressure on advertising budgets. New digital marketing and communications requirements have further claimed budgets previously allocated to print, which will continue to decline in absolute and relative terms

Recruitment has been the classified vertical with the most rapid print-to-digital transition, to the detriment of regional newspapers mainly. Online offers national reach at a fraction of the cost per listing

Unlike autos or property, recruitment is a fragmented vertical across a number of large job boards and niche sites serving identifiable professions

Facebook now has more than one billion users but future commercial success depends on monetising the growing consumption via mobile devices, which are replacing the PC as the main method of access

Facebook’s new mobile ads are newsfeed based Sponsored Stories and Promoted Posts rather than banners; early agency performance feedback is positive

Rapid growth in mobile ads will not be sufficient to offset slowing growth from PC-based advertising in 2012 and 2013, but revenue growth should pick up in 2014 as mobile ad volumes ramp up and other initiatives kick in

BT’s acquisition of Premiership Rugby rights underlines its intentions to create a solid premium sports channel with expected launch in summer 2013

BT’s entry into the sports arena is part of a wider TV platform/content strategy that embraces the launch of a much enlarged basic channel offer, integration with YouView and fibre roll-out

Although expected to post significant losses on its sports channels over the next three years, BT’s commitment appears long term

Search remains the main engine for Google’s core business, but display is rising fast: we estimate display gross revenue will reach $9.2 billion in 2013, representing 16% of projected gross revenue (excluding Motorola)

Gross revenue from YouTube looks set to more than double to nearly $4 billion by 2013. Revenues from Google’s ad networks and platforms are also growing strongly, mainly to the benefit of publishers

We project Google’s net revenue from display next year will amount to $4.2 billion, equal to 10% of net revenue from its total advertising business

Netflix returned to profit in Q2 2012 with results that were largely in the middle to upper range of its Q2 guidance estimates Underlying concerns remain about the ability of Netflix to deliver profit growth as it expands its international business due to weaker than anticipated growth in its core business of domestic US streaming subscriptions Reaching one million subscriptions since the January launch of Netflix’s streaming service in the UK and Ireland points to a marked slowdown during Q2 2012, suggesting breakeven will occur during 2014 at the earliest

Sky has launched NOW TV, an unbundled internet video service offering non-Sky households pay-as-you-go access to select Sky content, starting with movies, with sports added later in the autumn and TV shows to follow NOW TV addresses the growing opportunity for broadband TV, primarily appealing to the 8 million non-pay-TV households that have broadband – the same target audience as Netflix, LoveFilm, BT Vision and YouView We expect NOW TV to have only incremental impact on Sky’s financials, but it has the potential to put Sky in pole position in the nascent market for over-the-top TV

YouView, the hybrid DTT/IPTV service backed by the public service broadcasters, is here, but with an initial retail box price of £300 it will be heavily dependent on the subsidies offered by ISP distributors BT and TalkTalk The TV market has evolved since YouView’s conception in 2008, with many other internet-enabled options now available; its managed and integrated approach gives it some advantages but doesn’t make it a ‘must have’ We expect YouView to mainly appeal to Freeview and BT Vision upgraders and project take-up between 1-3 million TV homes by 2015, though if the product improves and pricing falls dramatically it could see faster growth
