What is a VTuber?

VTubers have seen a surge in popularity in recent times, enchanting audiences with an intriguing fusion of entertainment and cutting-edge digital features.

The trend is often attributed to Japanese vlogger Ami Yamato, who burst onto YouTube with a 3D avatar back in 2011. Though some critics believe Ami leaned more towards 3D vlogging than true VTube, her innovative content undeniably paved the way for the VTube movement.

Yet, it took another six years for the term to be formally introduced. The Japanese vlogger, Kizuna AI, coined "VTuber" in 2017 and is often credited as the very first "virtual YouTuber." Kizuna AI sparked inspiration across the globe, turning VTube into an international sensation.

By 2018, the VTube wave had firmly taken root, with creators extensively using virtual characters as their on-screen avatars. This trend led to the rise of entities like Nijisanji and Hololive, both of which branded themselves as virtual talent agencies. 

The 2020 global pandemic further boosted VTube's momentum, broadening the audience for virtual vloggers. According to data from tech firm UserLocal Japan, the virtual vlogging sector has seen an astounding 1600% growth since its inception by 2021. It's forecasted that by 2029, the industry will be valued at $22.41 million.

In the still-evolving world of VTubers, there's already a rich vocabulary of specific terms, one of the primary being the "debut".

A VTuber debut marks the moment a new avatar steps into the virtual world, introducing itself to viewers and establishing its unique online identity. Debut videos often offer an in-depth exploration of the character, from daily habits to life backstory, and from aspirations to other personal details. It's this introductory video – the debut – that usually sets the trajectory for the VTuber's virtual journey and shapes the tone of their future content.

The VTuber model is the digital embodiment of the content creator. Whether in 3D or 2D form, this character mirrors the personality and aesthetic of the blogger. These models are designed to showcase the VTuber's unique attributes, right down to their hairstyle, outfit, and even facial expressions.

Animated in real-time, these models enable VTubers to engage with their audience, using a range of gestures and movements. 

An avatar, building upon the concept of the model, is a fundamental aspect of the VTuber experience. During live streams or video recordings, the content creator embodies this character. The avatar, manipulated by the VTuber in real-time, reflects their gestures and facial expressions. This methodology fosters a deeper connection with the audience, making the interaction feel more intimate and dynamic. Thanks to the avatar, content gains depth and immersion, giving viewers the sensation of communicating with a living individual rather than just watching a video or anime.

A VTuber voice pack adds a distinct and vivid touch to their avatar. It is the voice that the audience hears when the VTuber speaks or engages with them. Designed to resonate with the character's personality and style, the voice pack enhances the authenticity of the VTuber's content, fostering a deeper bond with the virtual persona. Often, seasoned voice actors are involved in shaping these voice packs.

To wrap up, the evolution of VTubers from their emergence in 2011 to their present-day global acclaim is a testament to the dynamic nature of the digital world. These virtual content creators have done more than just entertain; they have ushered in a new epoch of online self-expression. Drawing in audiences worldwide, VTubers underline the untapped and infinite potential of current technologies. Today, this potential is actualized by VTubers, the bold dreamers and innovators of the digital realm.
