Before the DVD full season releases, The X-Files had its episodes released in VHS season sets in parts of the world, as well as selected single episodes put together.
Each "wave" was three VHS tapes, each containing two episodes, for a total of six episodes per wave and two waves per season (for example, the home video release of Wave 1 drew from the first half of the first season: "Pilot"/"Deep Throat", "Conduit"/"Ice" and "Fallen Angel"/"Eve").
