BitTorrent, also referred to as simply torrent, is a communication protocol for peer-to-peer file sharing (P2P), which enables users to distribute data and electronic files over the Internet in a decentralized manner. The protocol is developed and maintained by Rainberry, Inc., and was first released in 2001.^[2]

To send or receive files, users use a BitTorrent client on their Internet-connected computer, which are available for a variety of computing platforms and operating systems, including an official client. BitTorrent trackers provide a list of files available for transfer and allow the client to find peer users, known as "seeds", who may transfer the files. BitTorrent downloading is considered to be faster than HTTP ("direct downloading") and FTP due to the lack of a central server that could limit bandwidth.^[3]^[4]

BitTorrent is one of the most common protocols for transferring large files, such as digital video files containing TV shows and video clips, or digital audio files containing songs. BitTorrent accounted for a third of all internet traffic in 2004, according to a study by Cachelogic.^[5] As recently as 2019 BitTorrent remained a significant file sharing protocol according to Sandvine, generating a substantial amount of Internet traffic, with 2.46% of downstream, and 27.58% of upstream traffic,^[6] although this share has declined significantly since then.^[7]
