Amazon has entered the increasingly crowded digital entertainment TV device marketplace, one which could be strategically more important for the ecommerce giant than tech rivals Apple and Google

The frictionless integration of entertainment and ecommerce on TV represents a bigger consumer milestone than competitor services are offering, and Amazon’s brand has huge appeal, though at present it has less market traction for streaming than it does for other products

Content owners and broadcasters remain the real TV gatekeepers, with integration of TV and digital a service-level pipe dream for now, and so Amazon will likely have to accept being one of many, rather than the runaway winner as it is in books

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.

Revenue at Twitter is now on a $600 million annual run-rate, scaling rapidly since the introduction of ‘native ads’, and seems set for further growth: the key question is whether it can achieve breakout user growth and mass market scale.

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

Happy Birthday iTunes! It is just over a year since Apple launched iTunes and the media continues to talk up the second coming of the music industry, whose saviour appears in the form of affable Steve Jobs. iTunes sold a total of 70 million tracks online in its first year, well below its target of 100 million, but a respectable showing, especially since it spawned a small flock of competitors determined to out-sell iTunes.
