The series was subsequently aired in North America on the Discovery Channel in 2000, with Branagh's voice replaced with that of Avery Brooks. It is the first entry of the Walking with... series and used computer-generated imagery and animatronics  to recreate the life of the Mesozoic, showing dinosaurs in a way that previously had only been seen in feature films. The program's aim was to simulate the style of a nature documentary and therefore does not include "talking head" interviews.

The Ballad of Big Al (distributed as Allosaurus: a Walking with Dinosaurs Special) is a combination biography-sequel for Walking with Dinosaurs . It focuses on an Allosaurus (Allosaurus fragilis) named Big Al and his constant struggle to survive in a world filled with danger.

It is narrated by Kenneth Branagh, and by Avery Brooks in the American version. Using state-of-the-art visual effects, this prequel to Walking with Dinosaurs shows for example how a two-ton predatory fish came on land to hunt. The series draws on the knowledge of over 600 scientists and shows nearly 300 million years of Paleozoic history, from the Cambrian  Period (530 million years ago) to the Early Triassic  Period (248 million years ago).

Sea Monsters was a BBC television program which used computer-generated imagery to show past life in Earth's seas. It was made by Impossible Pictures, the creators of Walking with Dinosaurs, Walking With Beasts and Walking With Monsters.

Life After People is a television  documentary series where scientists  and other experts speculate about what the Earth might be like if humanity no longer existed, as well as the impact humanity's disappearance might have on the environment and the artificial aspects of civilization. The program premiered as a two hour special on January 21, 2008 on the History Channel.  which served as a de facto pilot for the series that premiered April 21, 2009.

The program does not speculate on how humanity may disappear, only that it has, and that it has done so suddenly, leaving everything behind including household pets and livestock that have to fend for themselves. The rest of the speculation is based upon documented results of the sudden removal of humans from a geographical area and the possible results that would occur if humanity discontinues its maintenance of buildings and urban infrastructure.

Aftermath: Population Zero (also titled Aftermath: The World After Humans)  is a two-hour American special documentary film that premiered on Sunday, March 9, 2008 (at 8:00 PM ET/PT) on the National Geographic Channel. The program was produced by Cream Productions.

Similar to the History Channel's special Life After People, Aftermath features what scientists and others speculate the earth, animal life, and plant life might be like if humanity no longer existed, as well as the effect that humanity's disappearance would have on the artifacts of civilization.

The Future Is Wild was a British 2003 joint Animal Planet/ORF (Austria) and ZDF (Germany) co-production, which used computer-generated imagery to show the possible future of life on Earth.

Based on research and interviews with dozens of scientists, this documentary was put together to show how life could evolve in the future if Homo sapiens became extinct.

Alien Planet is a 94 minute mockumentary, originally airing on the Discovery Channel, about two internationally built robot probes searching for alien life on the fictional planet Darwin IV. It was based on the book Expedition, by sci-fi/fantasy artist and writer Wayne Douglas Barlowe, who was also executive producer on the special. It premiered on May 14, 2005.

Aurelia and Blue Moon are hypothetical examples of a planet and a moon on which extraterrestrial life could evolve. They are the outcome of a collaboration between television company Blue Wave Productions Ltd. and a group of American and British scientists who were collectively commissioned by National Geographic. The team used a combination of accretion theory, climatology, and xenobiology to imagine the most likely locations for extraterrestrial life and most probable evolutionary path such life would take.

The beginning concepts appeared in a two-part television broadcast called Alien Worlds, aired in 2005 in the UK by Channel 4. Channel 4 has also released a DVD of the programme. The show was also aired on the National Geographic Channel as Extraterrestrial and focuses more on the alien life on the two worlds.

The first program in the series focused on Aurelia, a hypothetical Earth-sized extrasolar planet orbiting a red dwarf star in our local area of the Milky Way. This hypothetical world might resemble the recently discovered real exoplanet Gliese 581 d. The second focuses on a moon called Blue Moon, which orbits an enormous gas giant that is itself orbiting a binary star system. In turn, Blue Moon and its parent gas giant may resemble HD 28185 b and 55 Cancri f, two other real exoplanets. The show blurred the lines between science fiction and science fact.

The Universe is an American documentary television series that premiered on May 29, 2007 on The History Channel. The program is produced by Flight 33 Productions and Workaholic Productions. The show features computer-generated imagery/computer graphics of astronomical objects  in the universe  and interviews with experts who study in the fields of cosmology, astronomy, and astrophysics.

Into The Universe with Stephen Hawking is a 2010 science documentary TV mini-series written by British physicist Stephen Hawking. The series was created for Discovery Channel by Darlow Smithson Productions and features computer generated imagery of the universe created by Red Vision.

A 12 episode weekly TV series for the Science Channel which first aired in the United States starting December 1, 2009. Hosted by Michio Kaku (who makes several appearances in The Universe series) and based on his best-selling book.

The show revolves around the science behind ideas that sound impossible right now, but might be quite possible in the future, themes such as Time Travel, Light Sabers, Space Travel and many others are covered over the first season.

Around March 22, 2010, Dr. Kaku will start filming for the second season of Sci Fi Science, which will consist of 12 new episodes. It is planned to start broadcasting in Fall 2010.
