The Digibox is a device marketed by Sky UK in the UK and Ireland to enable home users to receive digital satellite television broadcasts from the Astra satellites at 28.2° east. An Internet service was also available through the device, similar in some ways to the American MSN TV, before being discontinued in 2015. The first Digiboxes shipped to consumers in October 1998 when Sky Digital was launched, and the hardware reference design has been relatively unchanged since then. Compared to other satellite receivers, they are severely restricted. As of 2020, Sky Digiboxes have become largely outmoded, superseded by Sky's latest-generation Sky Q boxes and Sky Glass televisions; the previous generation Sky+HD boxes are still in use, however.
