 In 2007, Comcast, the largest cable company in the US, was found to be blocking or severely delaying BitTorrent uploads on their network using a technique which involved creating 'reset' packets (TCP RST) that appeared to come from the other party.An August 2007 report by TorrentFreak (based on substantial nationwide research led by chief researcher Andrew Norton) noted that ISPs had been throttling BitTorrent traffic for almost two years, since 2005, but Comcast was completely blocking it in at least some cases.This was later verified by both the EFF and Associated Press.
