AOL, famous for its dial‑up service and iconic "You've got mail" greeting, announced it will discontinue dial‑up Internet, AOL Dialer software, and AOL Shield browser on September 30. Once known for its trial CDs in the 1990s, the dial‑up connection linked users via telephone lines with a distinctive chirping sound. Now part of Yahoo, AOL was sold by Verizon to Apollo Global Management in 2021, according to NBC News.
