Bing quietly announced on Twitter that if you search for [on this day] in Bing you may just get an historical knowledge box showing you important and historical events that happened on this day in the past.
For example, today Bing shows these four events:
- Esperanto introduced
- FBI's origins
- Disney's 'Alice' premieres'
- The Hustle' hits #1
There is a calendar selector at the top to change the date and you can share this knowledge and search result on Facebook or Twitter.
Pretty cool search feature Bing, Google does not yet have it.
