Chatbots have existed since 1966 but have only recently been discussed as a business strategy due to advances in artificial intelligence and natural language processing. NLP allows AI systems to analyze human language in conversations to derive meaning, with the goal of making interactions between computers and humans feel just like interactions between humans.

Chatbots have been around since the early days of computers, with the first conversational
bot used in 1966. However, it has only been in recent years that chatbots have been
discussed in the context of business strategy. This influx in interest can be connected to the
recent advances in Artificial Intelligence (AI) and the development of Natural Language
Processing. NLP allows AI systems to analyze human language to derive meaning from
conversations, with the goal of making the interaction between computers and humans feel
exactly like interactions between humans.
