Was wondering so looked up how much YouTube lost per second.

> YouTube ads generated $15.15 billion in revenue in fiscal year 2019.

So plugged into wolfram alpha:

They lose about $480 per second or $1.7MM per hour. Yikes.

And we know that it isn't flat throughout the day. I imagine this is probably peak earning time for them, assuming they bulk of the revenue is US based.

Why MM, is it the standard for million akin to "k" is for thousand?

MM looks like "million million" to me, which is the old standard for billion but nowadays a billion is just a thousand million and a million million is a trillion and I am constantly feeling frustrated about how wasteful we are with words for big numbers.

But I think in this context MM is a million.

That was my exact thoughts seeing MM too yeah, the Roman M symbol meaning thousand clears it up though. Just a historical oddity.

"M" is the roman numeral for thousand. It is therefore ambiguous. Especially when dealing with money, you really don't want a million to be confused with a thousand.

MM means mil mil or 1000 1000. Its the roman numeral for 1,000,000 and typically used today in finance.

MM is 2000 in roman numerals though. It's additive, not multiplicative.

In finance mm is generally accepted to mean million.

"Mille" is French for 1,000. So MM = 1,000 * 1,000. M is also used in advertising, like CPM: Cost Per Mille.

Also plus the cost of losing users due to long term adverse effects of this incident.

I don’t think anyone is going to stop using YouTube because of a small downtime. There is really no alternative to it out there.

What about the new users visiting the site for the 1st time in that small downtime window? If their first experience sucks there is likelihood they won't come back.

So:

(number of new users) x (probability of those users not coming back) x (lifetime value of a youtube user) = I highly doubt this is equal to 0

I truly believe that the number of people that navigated to youtube for the first time ever in their lives during that window might actually be 0.

So you believe YT's growth rate == 0?
