In 2004, Google launched Gmail, a free email service that offered a significant amount of storage space (1 GB) and a clean, intuitive interface. Gmail's innovative features, such as threaded conversations and search functionality, quickly gained popularity among users. AOL (America Online), founded in 1985, also offered email services, but it wasn't until the late 1990s that AOL's email became widely used. AOL's email service allowed users to access their email, news, and online content through a proprietary software.
