ThinkPad's brand introduction was inspired by IBM's Pad. Every IBM employee or person who goes to the IBM training center for training will get a pad with the motto "think" printed on it. At a meeting to discuss the product name of portable computer, a participant casually threw such a notebook into the air and put it on the conference table. Inspired by this, another participant suggested using the name "ThinkPad". At first, IBM executives once opposed the use of this name because IBM has always used numbers to identify product models. However, the name "ThinkPad" is greatly welcomed and loved by employees and customers. Finally, IBM executives compromised and agreed to use "ThinkPad" as the product name.
