Jelly Bean is now on 10 Percent of Android Devices

While the slow adoption of Android 4.0 Ice Cream Sandwich continues, Jelly Bean is also picking up speed. The latest numbers directly from Google show that 29.1% of devices that recently accessed Google Play are running Ice Cream Sandwich. 4.1 and 4.2 Jelly Bean combined are now on 10.2% of devices. Jelly Bean has passed the 10% milestone a few months earlier than Ice Cream Sandwich did, which was in July when the Nexus 7 was released.

Android Adoption - January 3rd 2013

The rate of adoption is so fast probably because Samsung has been pushing Jelly Bean to its flagship phones.
