Biography is a documentary television series. It was originally a half-hour filmed series produced for CBS by David Wolper from 1961 to 1964 and hosted by Mike Wallace. The A&E Network later re-ran it and has produced new episodes since 1987. The older version featured historical figures such as Helen Keller and Mark Twain, or long-dead entertainment figures such as Will Rogers or John Barrymore. The A&E series has placed the emphasis on such people as Marilyn Monroe, Elvis Presley, Plácido Domingo, Freddie Mercury, Jacqueline Kennedy Onassis, Eric Clapton, Pope John Paul II, Gene Tierney, Selena, Diego Rivera, Mao Zedong and Queen Elizabeth II, and fictional characters like The Phantom, Superman, Hamlet, Betty Boop, and Santa Claus. The program ended up profiling enough figures that in 1999, A&E spun it off into an entire network, The Biography Channel.

MegaStructures is a documentary television series appearing on the National Geographic Channel in the United States and the United Kingdom, Channel 5 in the United Kingdom, France 5 in France, and 7mate in Australia. Each episode is an educational look of varying depth into the construction, operation, and staffing of various structures or construction projects, but not ordinary construction products. Generally containing interviews with designers and project managers, it presents the problems of construction and the methodology or techniques used to overcome obstacles. In some cases this involved the development of new materials or products that are now in general use within the construction industry. MegaStructures focuses on constructions that are extreme; in the sense that they are the biggest, tallest, longest, or deepest in the world. Alternatively, a project may appear if it had an element of novelty or are a world first. This type of project is known as a Megaproject.
