Around the turn of the millennium, there were already numerous pedagogical agents, i.e., chatbots, voice assistants, and early social robots in learning environments. Names such as Virtual Learning Companions (VLCs) were also commonly used for the purely virtual versions. One of the companies that was ahead of its time was Extempo Systems, Inc. based in Redwood City, California. The company had evolved out of the Stanford Engineering School and designed and developed commercial agents for entertainment, business, and education: „Extempo makes e-learning products that help corporate em­ployees perfect their people skills. The company’s approach allows every learner to achieve mastery of the people skills they need for effective management, teamwork, sales, customer service, and other critical business functions. Extempo’s products give learners authentic practice in a variety of job-specific conversational role-plays, along with expert individualized coaching throughout the learning process.“ (Extempo Systems) One example was the virtual Nina, with whom you could communicate and who you were supposed to motivate to behave in a certain way. It wasn’t just the functionality that was impressive at the time, but also the design of the characters.
