In an audacious move to minimise the risk of mobile social disruption, Facebook is to acquire leading messaging app Whatsapp for up to $19 billion, or $42 per user, or 11% of Facebook’s current market cap

Messaging platforms are becoming the new social media, particularly for younger demographics, and while Facebook/WhatsApp will be huge in mobile, other services could still side-step into Facebook’s territory

The price for WhatsApp may be justifiable to counter the threat, but Facebook has only bought one of many, and paying a full price may encourage the others; expensively buying every competitor does not feel like a long-term strategy

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.

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
