According to Canalys, 4.6 million wearable bands were shipped in 2014. Out of those, 720,000 were Google-powered (mostly Android Wear). Canalys says that the Moto 360 was the clear leader of the Android Wear devices, and LG's G Watch R (with its round flexible OLED display) was more popular than LG's previous square watch.
While Android Wear's numbers aren't stellar, other smartwatch platforms aren't very successful either. Canalys says that Pebble sold a million devices since its launch and Samsung is also "struggling to keep consumers engaged".
