Google hasn’t exactly revealed sales figures of the Chromecast, but it did say soon after the launch of this HDMI dongle that they had underestimated its demand. This $35 dongle became an instant hit soon after it was launched last year, and even though its only available in the U.S. right now, there has been speculation that it is ready to go global. At SXSW today, Google’s Android chief Sundar Pichai told attendees that Chromecast sales are now in the “millions,” and that they are continuing to grow very actively.

Pichai also said that in the coming weeks Chromecast is going to be released in more countries, however he didn’t detail exactly which countries will be the first after the U.S. to receive this popular dongle. Previous rumors suggest that the UK might be the first international stop for Chromecast, a UK retailer had its availability listed for March 1st but that was later clarified to be provisional.

It remains to be seen how soon Google is able to launch Chromecast officially in other countries, pricing would obviously vary by region and country. The $35 dongle does a bang up job of streaming content to a TV, and now that its SDK has been opened up, developers have been creating some very interesting applications for it.
