BBC controller of arts commissioning Roly Keating defended the move, saying "the documentary strand will be able to tackle a wider range of subjects." Regarded as its "flagship arts programme", Omnibus was one of only two regular arts platforms broadcast at the time by the BBC.

In late 2002, the BBC announced that Omnibus would be cancelled the following year, to be replaced by the arts series Imagine, hosted by Alan Yentob.
