Despite this, the latest Digital TV Research report forecasted that on-demand services like Netflix will still represent less than 3 per cent of total television revenues in 2018.
Meanwhile, other research from GfK into the habits of online video subscribers indicated a very wide variety of viewing and noted that episodic or "niche" viewing was becoming a trend. Users seemed more likely to watch the kind of programmes or films they might otherwise rent on DVD rather than content that they might see broadcast on traditional television networks. To compete, on-demand needs to become more like broadcast television. Reed Hastings, the chief executive of Netflix, has said his goal is to "become HBO faster than they can become us".
Netflix has already had some success in this regard, receiving nine Emmy nominations for its remake of House of Cards, a series that was broadcast exclusively online and on-demand. However, Netflix and other online services are coy about how many people actually watch, even though they certainly collect detailed information about this. BARB will begin reporting online viewing for major UK broadcasters by the end of the year.
Another concern associated with the new television landscape is that the mass audience is becoming a thing of the past. There is more content than ever and that content can be watched wherever, whenever. This shift is fuelled by the rising availability of connected devices that can be used to watch television. Ofcom's recent Communications Market Report revealed that the average UK household has more than three internet-enabled devices (my household has eight).
These devices can be used not only to watch programmes but also to multi-task in front of the television, becoming a source of distraction from viewing. Much of what we do with our devices while the television is on is unrelated to what's onscreen: email, browsing, and even watching other content. Household members may sit in the living room together, but they are no longer engaging with the same things as a group in the way that families used to watch programmes together.
But Ofcom also reported that a quarter of people in its survey use devices to do something connected to television while they're watching. So-called "media meshing" might involve searching for additional information about what they are seeing on screen or using a tie-in app (though these are still rare).
But the most talked-about media meshing activity must surely be social media use. As the industry takes stock after Edinburgh, this phenomenon and how to react to it will undoubtedly be the subject of much discussion.
TV Licensing has highlighted the influence of online social interactions, which it dubs "chatterboxing". It's a practice that is most widespread among those aged under 35 and most commonly involves talking about a programme on websites such as Twitter or Facebook.
Broadcasters have cottoned on to the phenomenon already and have started to take steps to react, such as displaying tweets from viewers on screen during a broadcast and attempting to interact with viewers through social networking sites.
But they could be doing more. Where many other types of media use might be seen to be taking viewers away, chatterboxing can actually serve to reinforce more traditional television viewing habits. It can reinforce the desire to watch programmes live in order to avoid spoilers and a good buzz also serves to recommend programmes. Viewers may no longer be watching television with the family they live with, but they are viewing together as an online family.
In Britain, BSkyB appears to have worked this out and last year invested in Zeebox, an app to promote the benefits of media meshing by integrating social media and content, offering synchronisation even with recorded shows, personalised recommendations and virtual rooms for fan communities.
Despite these changes, Ofcom's report also stressed continuity, even nostalgia, in UK viewing habits. It pointed out that 90 per cent of viewing in 2012 was broadcast television, and that sports and other live events are still watched in the living room on screens that are getting larger.
Interestingly though, YouGov research shows that 60 per cent of content watched on portable devices is also live (news and sport) and can't be comfortably time-shifted. It seems that we will consume unmissable content on the biggest screen available at the time. And it could be argued that we have a more intimate relationship with the small screens that we carry around with us, even in some cases into the bathroom.
The actions of consumers - our choice of devices, subscriptions, apps, and social media - will have decisive impact on the future shape of television. The television viewer has traditionally been characterised as a couch-potato. Now it seems our actions will dictate the opportunities for innovation and creativity.
