The original broadcast versions of some episodes were briefly released in Japan on laserdisc in 1993 and on VHS in 1994. However, Lucas drastically reedited and restructured the show for its worldwide home video release. Major structural changes were made, including the complete removal of the 'bookend' sections narrated by the 93-year-old Jones, and the editing of all the one-hour episodes together into two-hour episodes. Approximately half of the series was released on VHS in various markets around the world in 1999, but the entire series was not released until its DVD debut, in a series of three boxsets released from 2007 to 2008, to tie in with the theatrical debut of "Kingdom of the Crystal Skull". Among other extras, the DVDs include approximately 100 new historical featurettes.
