What happened that year?
An invention can have several milestones. The clue asks for a specific one: a discovery, a first working demonstration, an announcement or a commercial launch. Guess that event’s year. The reveal gives its context and a link to the source.
- The first iPhone
- Apollo 11
- The World Wide Web
One good guess leads to another.
