In 2005, Thomson Multimedia acquired Canopus to bolster their Grass Valley broadcasting and network product line.

Canopus had a reputation for driver optimization that gave a performance advantage over other cards.

They were the cards of choice for Maximum PC's 1998 Dream Machine.

Canopus also released a version of the nVidia TNT that offered a unique internal cable that connected the TNT card to the Voodoo2 based Pure3D II—as opposed to the standard connection with an external cable.

Canopus is also known for EDIUS, non-linear video editing software, and a transcoder application called ProCoder, and their ADVC range of DV (IEEE1394) video conversion units.
