Monkeys have been embracing video streaming.
A monkey media player has allowed the primates to watch videos or listen to audio on a screen in their enclosure at a zoo in Finland.
During trials, the white-faced sakis flicked between three options by triggering infra-red sensors. The screen was activated if a monkey passed the sensors and switched off when they lost interest - often after a few seconds.
The experts found that the sakis selected audio content more often than video footage but not enough to show if they had a preference.
Dr. Ilyena Hirskyj-Douglas - who led the research for the University of Glasgow - claimed that further tests would show whether the player boosted the animals' quality of life.
She said: "It's the first time we've given them the option of video or audio content. Our findings raise questions which are worthy of further study to help us build effective interactive systems."
