We live in a many-device, media-rich, connected world. But despite the great diversity of screens we regularly engage with, one still plays a prominent part in our homes – the television. While, previously, we might have browsed a paper magazine while half-watching a TV programme, today we are more likely to be interacting with handheld devices. In the pre-digital era, choreographing and combining TV content with the viewers’ other media was virtually impossible. Now, broadcasters and independent application designers are doing so, and are seeking ways to ensure that experiences that span devices are engaging, effective and congruent. This article addresses the critical issue of sup-porting users in managing their attention across devices; uncovering the key at-tributes of experiences in which two or more devices are complementary.
