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.

Next-generation consoles from Sony and Microsoft, expected late this year/early next, will kick off a new cycle for the games industry, but enter a much more competitive market

Smartphones and tablets offer an alternative gaming model, with more variety, lower cost, greater convenience and, crucially, rapidly increasing sophistication

These new platforms are expanding gaming to a much larger audience, but also increasingly competing with consoles for the time and attention of core gamers. This could be the last recognisable console cycle

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.
