After two centuries of vaccination campaigns, the World Health Organization declares that smallpox is eliminated across the globe.

3M releases Post-It® Notes, with an adhesive strong enough to stick to a surface - such as a page in a book - but easily removable without any sticky residue.

The notes become a handy way to communicate at home and at work.

3M also releases Scotch® VHB® (Very High bond) tapes.

The very strong tapes replace rivets and screws in fastening operations.
