ELI5: How does youtube meet the incredibly high demand for storage required for all the uploaded videos?

I read that if you tried to watch every video on youtube, for every minute of video you watched, you would fall one week behind due to all the uploads that would take place in that one minute.

So this raised the question - how does youtube (or Google) meet such an incredible demand for storage? Are there algorithms that make video storage size smaller? And even if such algorithms existed, wouldn't there still be an absolutely atrocious amount of data that would need to be stored?

And you continuously add more drives.  By the rackful.
