Google Chromecast already a big hit in the UK and Norway, inventories reportedly sold out

According to some retailers, the launch day of the gizmo was rather successful, as a single Chromecast got sold each 4.5 seconds in Currys, a popular store chain. This made the Chromecast's debut "one of the most successful launch days" both online and in brick and mortar stores recently. Some retailers even likened the dongle to the Apple iPad in terms of user interest.
“We’ve sold millions of Chromecast to date, and we hope to replicate that success in Europe,” revealed a Google representative.
This is not the first time the Chromecast proves that it's very successful – Google quickly sold out its inventories during the US launch of the gadget. The Mountain View giant also placed the Chromecast alongside with the Nexus 5 in the list of its best-selling and most successful devices.
