YouTube-related numbers

YouTube is a video service currently owned by Google and founded by three former PayPal employees, Chad Hurley, Steve Chen, and Jawed Karim. It is among the most popular online video sites as of June 2017undefined, and has received much attention by individuals of all ages. This page is dedicated to listing numbers which have significance in the YouTube community.

Class 1
301: Before August 2015 a YouTube video would freeze at 301 views in an effort by YouTube to validate the views received on a video which becomes popular in the community. The matter is more fully explained in the Numberphileundefined video Why do YouTube views freeze at 301?undefined, (note as an in-joke the video happens to be "frozen" at 301 views, though by now it has received over 4.1 million).

Class 2
73,786,976,294,838,206,464: The number of different eleven-character video ID's. The derivation is as follows:


 * There are 64 possible characters to choose from for each character, (52 for lowercase and uppercase English letters, 10 for the digits zero through nine, and 2 for a hypen, -, and an underscore, _).


 * There are 11 characters in total, therefore the number of possible video ID's is \(64^{11}\), or 73,786,976,294,838,206,464.

Informative YouTuber Tom Scottundefined has uploaded a video entitled Will YouTube Ever Run Out Of Video IDs?undefined, which presents the following derivation in a slightly longer way.

22,300,745,198,530,623,141,535,718,272,648,361,505,980,416: The number of different 24-character channel ID's. The derivation is as follows:


 * There are 64 possible characters to choose from for each character, as explained in the prior proof.


 * There are 24 characters in a channel-ID, therefore there are \(64^{24}\) possible channel-ID's.
