I don't know that creamed corn on its own is "the rage" - though corn (look up elote) is coming into it's own again in various recipes because it has always been a popular Mexican street food, and those recipes have traveled north with immigrants (or evolved here with native North Americans who grew it in the American Southwest, in particular).

The creamed corn variety I've always thought of as a New England dish, but that video clearly lays a southern claim to it (I think they might best claim the adding milk and butter part of it.) It was always something we had a few cans of when I was a kid - it was treated like a vegetable, but of course, maize is a grain. It was an addition to a meal that needed something more. Canned whole corn also was on the shelf, and I always have a large bag of frozen whole corn handy for various uses.
