In the midst of a pandemic, it might make sense for an increasing percentage of onscreen text to be numbers, reflecting a greater reliance on statistics and counts. The timeline below confirms this, reporting the total percentage of non-punctuation text each day on CNN since January 25th that was a number. In more precise terms, for each day, it sums up the total number of number characters and divides it by the total number of combined letter and number characters, showing a rampup starting around Feb. 15 and stabilizing around March 18th at its current level.

Constructing the timeline above took just a single SQL statement.
