A new survey of 2,148 people from YouGov, for FirstSource Solutions, found that 54% of 18-24-year-old Britons would rather watch catch-up TV on their computers than by any other method.
This was in contrast to 16% of 18-24-year-olds who would choose to use set-top boxes to watch catch-up TV.
Those taking the survey were asked: "Which ONE, if any, of the following is your preferred method of catch-up?"
Taking into account all age groups, 30% who would rather watch catch-up TV on a computer, with 19% across all age groups having a preference for set-top boxes.
Only 9% of the 18-24-year-olds polled said that they use set-top boxes to record programmes in advance, compared with 27% of all age groups.
DVD and Blu-ray box sets struggled to match the streaming services, with only 2% of Britons - and 5% of 18-24-year-olds - picking the optical media as their preferred catch-up method.
Despite increasing smartphone use, only 1% of Britons said that they used an online player on their handset to watch catch-up TV. The figure rose to 3% for those using online players via a tablet computer.
