Most international broadcasts such as Olympic Games coverage originate from a limited area for worldwide distribution. 2000 Today was rare in that its live and taped programming originated from member countries and represented all continents.
2000 Today was conceived as part of the so-called Millennium celebrations, given the numerical significance of the change from 1999 to 2000.
The program was produced and televised by an international consortium of 60 broadcasters, headed by the BBC in the UK and WGBH in the US. The BBC provided the production hub for receiving and distributing the dozens of international satellite feeds required for this broadcast.
The program's theme song was a version of Bob Marley's song "One Love" performed by The Gipsy Kings, Ziggy Marley, Tsidii Le Loka and the Boys Choir of Harlem. Sony released a soundtrack CD for 2000 Today which included this song plus A World Symphony for the Millennium by Tan Dun.
Most nations that observe the Islamic calendar were not involved in 2000 Today. However, a few predominantly Muslim nations were represented among the programme's worldwide broadcasters such as Egypt (ETV) and Indonesia (RCTI).
Africa was minimally represented in 2000 Today. The only participating nations from that continent were Egypt and South Africa. Portugal-based RTP Africa distributed the program to some African nations.
Antarctica was mentioned on the program schedule, although it was unclear if 2000 Today coverage was recorded or live.
2000 Today's core international broadcast was almost 26 hours long, following the beginning of the New Year 2000 across the world's time zones.
The program was tailored by individual broadcasters to provide local content and hosts.
The international broadcast began 31 December 1999 approximately 09:30 UTC. 2000 Today went international at 09:40 UTC, with the Kiribati Line Islands celebrating the arrival of 2000 at 10:00 UTC.
Most of Europe celebrated midnight on 31 December 1999 23:00 UTC. Broadcasting celebrations from many countries under Central European Time posed a particularly complex broadcast challenge. 2000 Today chose to rapidly air each nation's midnight observances in succession, using tape delays in most cases. This hour of the broadcast included a blessing by Pope John Paul II from Vatican City.
2000 Today's international feed ended shortly after midnight celebrations were broadcast from Samoa on 1 January 2000 at 11:00 UTC. BBC One in the United Kingdom continued its broadcast with national features until 13:30.

The following nations broadcast 2000 Today. Some nations were licensees of the broadcast, rather than formal members of the broadcast consortium.
