How These Three YouTubers Got Their Channel Names First one is MrBeast He got his name from a randomly generated Xbox Gamertag, MrBeast6000, and later removed "6000." His name became a strong and popular You Tube brand. Second one is IShowSpeed He was called "Speedy" as a kid and combined it with "I Show" to make his PSN gamertag, which later became IShowSpeed. Last one is kaicenat He got his channel name directly from his real first and last name, choosing to use his real identity to make his brand simple, memorable, and consistent.
