From their recent 10Q for investors, they list a revenue of $7.8 billion for "Google Network" in revenue for the preceding 3 months before September 30, 2022 [1] There are 90 days in 3 months, so their revenue for a day is approximately

$7.8 billion / 90 days = ~$87 million/day

$87 million / 24 hours = ~$3.64 million/hour

$3.64 million / 60 minutes = ~$60,740 thousand/minute

$60,740 thousand / 60 seconds = ~$1,012/second

And, depending on their agreements with their advertising partners, they might be liable for some of the profits lost by their partners.
