LineOne was an Internet service provider in the United Kingdom in the 1990s. LineOne was a joint venture of News International, United News & Media and British Telecom. It then became the UK branch of Tiscali, which is now TalkTalk.
As of October 2017, the "lineone.net" domain is still active for email (username@lineone.net) and website hosting (website.lineone.net/~username). More recently (October 2019), TalkTalk has notified LineOne customers that from 10 December 2019, unless they pay £5 per month or £50 per year or sign up to the TalkTalk broadband service, they will lose most Talk Talk features, will only have access to their mails through webmail and will start closing down free e-mail accounts.
History
Before LineOne was launched in 1997 as a joint venture between News International and British Telecom, it was known as Springboard Internet Services and previously to that Delphi. This is not to be confused with, although it's related to, the company known as Delphi in the United States which had been purchased by News Corporation shortly before, and then sold on, and whose embryonic UK offerings were overseen by News International. Andrew Burke was the founding CEO and had previously run News International's Internet Publishing division responsible for putting The Times, Sunday Times, The Sun, News of the World and Today onto the web as well as Delphi in the UK.
