Time tourism

Time tourism, also referred to as temporal tourism, (PROSE: A Rough Guide) was a form of tourism in which time tourists time travelled to famous or desirable points in history. Often this was organized by companies such as Nostalgia Tours, (TV: Delta and the Bannermen) Jolly Chronolidays, Past Perusals, (AUDIO: Omega) and Yesterways LTD. (PROSE: Possum Kingdom)

Time tourists frequented parts of Earth history such as ancient Athens, (AUDIO: Mask of Tragedy) the life of Richard III of England, (AUDIO: The Kingmaker) and 1950s Disneyland. (TV: Delta and the Bannermen) Gallifreyan history was also a common point of interest. (PROSE: A Rough Guide, AUDIO: Omega)

During the Seventh Doctor's lifetime, time tourism was regulated by the Time Lords, who provided the Navarinos with limited temporal capabilities. (PROSE: Return of the Living Dad) However, temporal tourism was less regulated further into the future beyond the Time Lords' domain. (PROSE: A Rough Guide, AUDIO: Omega)

During the multiverse collapse, Earth's timeline was massively destablized by the company Good Times offering time travel tours to every point in history, thus commercially sanitizing every culture at every point in time. (PROSE: The Last Resort)
