"Meta" had been registered as a trademark in the United States in 2018 (after an initial filing in 2015) for marketing, advertising, and computer services, by a Canadian company that provided big data analysis of scientific literature.[89] This company had been acquired in 2017 by the Chan Zuckerberg Initiative (CZI), a foundation established by Zuckerberg and his wife Priscilla Chan, and became one of their projects.[90] Following the Facebook/Meta rebranding announcement, CZI announced that it had already decided to deprioritize the earlier Meta project, that it would be transferring its rights to the name to Meta Platforms, and that the project would be sunset in 2022.[91]
