In recent years, services based on "retrieval-augmented generation," which combine generative AI with search engines, have spread rapidly. In addition to utilizing data learned previously, these services search for the latest information online and present shortened answers. They are said to be able to provide more accurate and up-to-date information. However, rights holders who created the original content, such as newspaper publishers, fear that users may be satisfied with AI-derived responses, reducing visits to their own websites. There are also concerns about negative impacts on sales of article databases in addition to individual paywalled articles.
