what does the tv in twitch.tv stand for

The "TV" in Twitch.tv stands for television.

The founders of Twitch originally created the platform as a live streaming service focused on video games, and they chose the name "Twitch" as a reference to the way gamers often twitch their fingers when playing fast-paced games. The addition of ".tv" to the end of the name was a nod to the platform's origins in live streaming, which is often associated with traditional television broadcasts. Over time, Twitch has expanded beyond its gaming roots to include a wide range of content categories, but the name and domain have remained the same.
