For decades, families settled on the sofa to share the latest news and TV series, until additional bedroom TV, computer games and the Internet almost put an end to family rows over who held the remote control. Now, however, the traditional living room scene is making a comeback. A study by the communications watchdog Ofcom has found families are once again gathering around the main television set, but they are bringing their pads and smartphones with them.
“The 1950s living room is making a comeback as a family entertainment centre,” said Jane Rumble, head of media research at Ofcom. “We are watching on much better, bigger, and more delicate television sets, but we are coming into the living room holding our connected devices.” While the family are coming together once more, comparisons with the past end there. With a range of smaller screens on hand, not everyone sitting on the sofa shares the same viewing experience.
The coronation (加冕礼) may have drawn the undivided attention of 20 million viewers in 1953, but those watching the Queen’s Jubilee celebrations 50 years later were as likely to be commenting online about BBC’s broadcast as watching it. “Just a few years ago, we would be talking about last night’s TV at work or at school,” said a viewer, “Now, we’re having those conversations live while watching TV, using social media, text and instant messaging.”
It is a behaviour of media meshing(联网), whose influence was underlined during this year’s Wimbledon men’s tennis final. As Andy Murray pushed towards his victory, 1.1 million people worldwide sent an average of over two microblogs about the match.
People use the Internet to enhance their television experience, for example, by reading a newspaper live blog about a football match while watching the action on the main screen. For a huge number of younger viewers, the portable screen offers a chance to do something unrelated, such as online shopping, listening to music or watching another television programme.
Some 70% of 16-to-24-year-olds claim to be absorbed in what Ofcom calls “media stacking” at least once a week. For TV viewers, the Internet scanning is the most popular activity, but they are also calling friends on the phone or sending emails and texts. Surprisingly, 12% claim to have listened to the radio with the television on, and 6% say they have watched another video in the meanwhile.
