On 29 November, the Leveson Inquiry into the culture, practices and ethics of the press finally issued its report. Its verdicts on the conduct of the press, politicians and police were less severe than expected.

The three main political parties have accepted most of the report’s recommendations, but have disagreed over the use of statute. As expected, the Conservatives are against, while Labour and the Lib Dems are in favour.

Subsequent cross-party talks and negotiations between editors have so far failed to produce agreement, with the process only becoming more opaque as time goes on. The shape of the future regulatory system remains uncertain.

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

Around 125m smartphones were sold globally in Q2, up over 30% from Q2 2011. Around 450m mobile handsets were sold in the quarter, giving smartphones a volume share of around 28% Apple and Android dominate with a combined of 85% of units sold, and a cumulative total of 810m devices running their mobile platforms. Of these we estimate that 680m are active, of which 95m are tablets Android arrived later and has grown faster, but Apple’s market share of smartphones as been steady at 20-25% for several years: Android’s growth has come at the expense of Nokia, RIM and feature phones

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

Apple sold 67m iPads through March 2012, and retains over 70% market share for premium tablets. Apple is aiming for the same long term dominance it enjoyed with the iPod, which maintained similar market share for a decade Microsoft and Google are taking radical steps to try to change this. Both are now making and selling their own hardware, while Google will sell a tablet at cost Microsoft and Google now have coherent tablet propositions, but they remain far behind on broader app ecosystems. Like Nokia, they are now back in the game, but they still have to play

Google+, the social network, has around 100 million users worldwide, although user growth appears to have stalled and usage is low on weak network effects

Facebook users, now 70% of the adult internet audience (excluding China), have no incentive to switch to Google+, starving the social network of vital momentum

Facebook is likely to dominate socially enhanced search, unless Google+ takes off, which seems unlikely

We forecast print media advertising will be down by about 4% in 2012, with national newspaper display roughly flat, performances we envisage will be seen as a temporary reprieve once the substantially tougher 2013 that we expect to follow is underway

Print media is not out of the structural woods, and even relatively small revenue contraction will amplify pain as the opportunities for further streamlining fixed-cost physical distribution operations are realistically diminishing
