There are many initiatives to get people to know basics of programming. The current thinking seems to be that anybody can learn to code if concepts are introduced in the right way. Code.org‘s mission is to get coding into curriculums for students. It is known for example on projects like Computer Science Education Week and Hour of Code.
I can immediately see some similarities in Code Studio to MIT’s Scratch and Google Blockly. The Code Studio runs in your browser using HTML5 technology (=can run in most browsers, no installation needed). Besides providing the tutorial to K-5 .. K-12 students (or anyone who want to try), it provides an interface for teachers to monitor where their students are in the lesson progression. The Code Studio is available in several languages besides English (for example in Finnish).
Here is one screen capture of one tutorial:
