Usage of smartphones and tablets while watching television is rising, particularly among young adults. The Mediatel Connected Screens survey reports on usage of different screens in the United Kingdom, from televisions to computers, tablets and smartphones. Despite more ways of viewing programmes, traditional television still predominates. The survey found that 72% of broadband homes had a high-definition television and 4% claimed to have a 4K or Ultra HD set. Just 3% reported having no television. 90% of respondents said they watched television as it is broadcast at least once a week, with 69% saying they do so every day. 67% said they had ever viewed programmes they had recorded themselves, while 61% said they had watched an online catch-up service from a broadcaster, with 46% doing so at least once a week.
