Facebook has announced Home, an Android app that takes control of your phone, replaces the home screen with your Facebook newsfeed and relegates any competing social services to, it hopes, an afterthought.

At launch, Home will be available to at most 20% of Facebook’s mobile base. It is an interesting tool to lock in core users and drive up their engagement, but can only be part of Facebook’s mobile strategy.

Facebook has strong mobile user and revenue growth, but has not ‘won’ social on mobile as it has on the desktop, and competing services have drawn hundreds of millions of users. It is not yet clear Facebook will win, or even that there will be a single big winner.

The UK 4G spectrum auction raised a total of £2.3bn, broadly in line with similar auctions, although the highest quality spectrum raised less and the lowest quality spectrum raised more than might have been expected

The main short term consequences are as was expected beforehand; Vodafone and O2 will launch 4G services around May/June 2013 and H3G will launch in October 2013

Longer term, O2 and H3G may suffer from their lack of 2.6GHz spectrum, although with other bands likely to come free within the next ten years this may not affect them

Facebook’s announcement of Graph Search, the company’s first move into socially-powered search which now in beta trial in the US, leaves many details unanswered including full launch and monetisation plans. Reliance on user-generated content from Facebook friends limits the usefulness of Graph Search as a conventional search engine and hence its impact on Google and other web search businesses in the near term. In the longer term, Graph Search could become a powerful recommendation engine for certain categories like travel, but its dependence on user data and privacy restrictions are likely to limit its wider utility and revenue potential.

H3G’s H1 2009 results showed some improvement on revenue growth and profitability on a very weak H2 2008, but it is still growing very slowly while barely EBITDA positive

The company has at last admitted that it will not be EBIT positive in 2009, and without some major changes we doubt it ever will be

For the UK business, there are a number of factors which may turn in its favour over the coming two years, allowing a more concerted marketing push to scale; for Italy and the smaller European operation, consolidation appears the only answer

H3G group’s H2 2008 results showed a 5% decline in revenue on a constant currency basis and a return to strongly negative underlying EBITDA, with a margin of -17% in H2 2008 and -8% for the year as a whole, versus a margin of -1% in 2007

The UK performed reasonably well, with 11% revenue growth and improving margins, albeit still being cashflow negative, but Italy suffered from an 18% revenue decline and falling margins

The company’s target of positive EBIT in 2009 looks very unlikely without contributions from some major accounting adjustments, and the consolidation move in Australia looks likely to be repeated elsewhere

The planned merger of Vodafone and H3G in Australia has raised the question of what consolidation could occur in Europe, although a direct analogy is not appropriate because Vodafone is much weaker in Australia (#3 operator) than it is in the larger European countries, and so would face much more regulatory scrutiny in Europe

The only merger opportunities in the top five markets which would have a similar or lower theoretical impact on competition (and hence would theoretically be as easily approved) in the top five European countries would be T-Mobile and H3G in the UK, Wind and H3G in Italy, and any operator with Yoigo in Spain

There are massive cost savings to be had from in-market consolidation, with network, marketing and general administration costs all fully overlapping between operators. The non-merging players would also enjoy a period of less competitive intensity, which may last indefinitely
