If it wasn’t for the crossword puzzle book that Simon & Schuster introduced in 1924, I’d say that just like this day in 1930, nothing much has ever happened on April 18.
Newslite has more on the day without any news:
On April 18, 1930, during what should have been a 6:30pm radio news bulletin, that’s exactly what happened.
A BBC presenter announced “Good evening. Today is Good Friday. There is no news.” It had been apparently judged that nothing newsworthy had happened.
Piano music was then played instead of the current affairs update for a couple of minutes, before normal scheduling resumed.
