Stanley invented, or at least popularized, a new kind of tumbler. It is insulated to keep drinks hot or cold, it has large capacity but fits in cup holder, has handle to make easier to carry. I don't like since prefer smaller water bottles, but I understand why some people would. I also don't get the viral popularity, but I understand why social promotion of something people want and is new can take off. It is turned into phenomenon that people want just cause its popular.
