Google’s Chromecast is an appealing device, largely because it’s extremely affordable and allows folks to share content from iOS and Android smartphones right to their TV. We had no idea, though, that it’s so popular among consumers – not just the gadget-heads that read this site.

According to 9to5Mac, which listened in on Google’s earnings call last week, Google has sold 30 million Google Chromecast units, including the Chromecast Audio and the original Chromecast, since 2013, with about 5 million sold since May alone.

Sales figures might sound boring, so here’s why that matters: If Google sees these things flying off of store shelves and sees that consumers like its product, that means it’ll probably continue to develop Chromecasts and release new models and features. No idea when that’ll happen, but the Chromecast is certainly here to stay.
