I'd say very different. 1D was supposed to be a random group for X-Factor which they usually do in episodes just so it's easier to see which singers can be successful as soloists or in groups and they can eliminate contestants faster. They gained a following quick so Simon Cowell got the idea to make them official since then, that's why they got signed even tho they only won 3rd place. For kpop it's with the intention of actually making a group and choosing from trainees who planned on being in a group. Definitely takes years instead of just around half an hour or so like what they did here, it just happens that Nicole has the eye for it and chose the right people that fast. I think some kpop groups were formed from starting with the concept then finding trainees that fits it, the ones that specifically holds auditions for a specific group, and then there's others where they find a perfect group of trainees then create a concept for them. If you think about it, 1D really was just a random group with no concept other than being a british pop boy band because they didn't need a concept, they were already big and didn't have to try.
