I've seen something like this in action with young kids who are given a tablet and stumble upon cartoons they like on YouTube, but in a different language. After they watch a few cartoons, YouTube's recommender system keeps offering them more cartoons in that language. And it isn't long before they start spouting words and phrases in that language.
