Ant N Dec Productions was a 50:50 joint venture between Ant & Dec and Zenith, but after the first year of SM:TV Ant & Dec decided to take a step back from the business side of things and it was reworked so that Zenith would take over production and give Ant & Dec a development deal so that they'd still have creative control.

I think Ant and Dec Productions was pretty much just a label rather than a fully-fledged company, and all their shows, from The Ant and Dec Show through to SMTV, were basically Zenith Productions.
