Cathode-ray tube
I reverted your change to Cathode-ray tube because you are trying to change a sentence that is supported by references, and you have not provided any explanation for why you think it should be changed. The fact that User:JotP 2005 tried to change the same date to a different new date yesterday further reduces the credibility of your edit. --Srleffler (talk) 03:11, 15 March 2022 (UTC)
