That '70s Show was released on DVD in Regions 1, 2 & 4 by 20th Century Fox Home Entertainment at an increment of two seasons per year.
The complete series was released in Region 1 on October 14, 2008, the Canadian cost being almost double the U.S. price.
The DVDs contain various bonus features, such as the original promos for the episodes that aired on Fox on the original air date, retrospective interviews with various cast members, and commentaries by director David Trainer on selected episodes.
The music that featured many popular bands was predominantly removed or replaced with stock music on the DVD releases, in order to avoid paying royalties to the artists involved (unlike the actual run of a series, where studios would only have to pay royalties to the artist for that single episode, and maybe for syndication).
On May 4, 2011, Mill Creek Entertainment announced that they had acquired the rights to re-release the series on DVD in Region 1.
