While the SG-1 team is on a Goa'uld mothership, O'Neill asks Teal'c if the Goa'uld "TV" gets Showtime, a reference to the Showtime network on which the series aired from 1997 to 2002. On Hulu circa 2018, Jack's line was changed to, "mmm, Goa'uld TV." But the closed captioning subtitles didn't get changed, so they still make the Showtime reference.
During the scene where Carter and Jackson are watching the Jaffa enter the death gliders, you can clearly see a Jaffa in a glider on the far right side of the screen "raising the roof."
The shot of the four people running in the active Stargate in the beginning credits during the early seasons comes from this episode.
A scene with a Goa'uld mothership passing Saturn on its way to Earth is most likely an homage to a similar scene in The Best of Both Worlds: Part 2 (1990) where a Borg cube passes Saturn on its way to Earth.
After this episode, and the initial airing of the first season in Sweden, it would take another 5½ years before the second season would finally air. Although the initial airing garnered huge interest among Swedish sci-fi fans, the network lost faith in the show, even though the show was in its fifth season production-wise at that point. After changes of time slot, and several reruns partly on a different sister channel, they finally called it quits in the middle of the third rerun of season 1. It would then take another 5 years before the show was picked up again by the network on a new sister channel (TV6), which by then had profiled itself as Sweden's unofficial sci-fi channel, and a continuous airing of all 10 seasons during weekdays began. Due to the extreme tempo of this airing, the network did catch up pretty well by the end of the series, and the finale aired only four months after USA, compared to the premiere of season 2 that was almost nine years behind.
