At launch, Google’s new subscription service YouTube Red competes most directly with premium music streaming services, also offering ad-free videos

YouTube’s augmented revenue model re-boots incentives for native talent to produce content for the platform, and will also widen its appeal for established content producers

Although consumers are likely to find paid subscription for ad-free videos a weak proposition, Red holds much potential for YouTube as it competes for attention across device ecosystems, and presents little risk to its existing advertising model

The Game Developers Conference (GDC) and Mobile World Congress (MWC) saw major announcements in virtual reality and new generation streaming game consoles, as well as further opening up of access to game engine software

Latest earnings reports show that major publishers and developers are currently in buoyant form as growth in the PlayStation 4 and Xbox One install base boosts revenue and consumers migrate to digital sales

Results for developers dependent on the mobile or online ecosystem are more mixed: King (producer of Candy Crush) continues to grow, but Zynga is struggling, although recent performance hints at a possible halt in its decline

Microsoft dominated PCs and Nokia mobile phones, but both are irrelevant in the dominant model for tech in the next decade, smartphones and tablets. An acquisition may have been necessary, but by itself it solves nothing.

Smartphones are now half of all mobile phone sales, and the 255m smartphones and tablets sold in Q2 2013 dwarf the 76m PCs sold. Microsoft now powers less than a quarter of all the personal computing devices being sold.

Microsoft retains a leading position in enterprise and in console gaming. But if it cannot return to relevance in consumer, the strength of the whole business will suffer.

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
