Narrator: You probably recognize this. It's a Lightning cable. They're everywhere. In 2012, we said goodbye to 30-pin, and Lightning became Apple's main connector. But, seven years later ...

Lightning is one end of the cable, with USB Type A at the other. Introduced in 2012 with the iPhone 5 and new iPods, Lightning superseded the 30-pin dock connector that dates back to 2001.

The Apple device contains the socket, and the cable or docking station has the plug. In 2012, the original 30-pin analog+digital interface was replaced with the 8-pin all-digital Lightning connector.
