1990

British computer scientist Tim Berners-Lee invents the World Wide Web, the system of interlinked pages on the Internet.

Berners-Lee also develops the uniform resource locator (URL) that identifies Web resources and the Hyper Text Markup Language (HTML) used to design them.

After a decade of development, 3M introduces its DiamondGradeâ„¢ Reflective Sheeting.

Designed with microprisms, the sheeting is widely used on traffic signs to brighten their appearance in dark and stormy conditions.
