I just looked into this topic. I thought I missed something since it's been many many moons that I've attended college. More and more often I would see words like realize organize omitting 'z' for a 's' I HATE IT, it's even happening on my TV when I use closed captioning. But I guess it's something I'm going to have to get used to it. Internet and social media are global. I think it must be confusing for youth in America, words that are not listed in our dictionary, being spelled that way?
