<human>:  Where does the word ‘brainstorming’ come from?
<bot>: The term brainstorming was coined in the 1940s by Alex Osborn, who was an advertising executive. He was frustrated with the process of coming up with creative ideas for advertising campaigns. He believed that a group of people should be able to come up with many more ideas than they could by themselves. He came up with the idea of brainstorming, which he thought would allow people to think creatively together.
