Ion differs from other commercial networks in that the majority of its stations are owned-and-operated by its parent company with very few affiliates, and it is distributed exclusively via cable and satellite in markets where the network does not have a local station; Ion was the last of the seven conventional English language commercial broadcast networks to expand into distribution via digital multicasting, having relied entirely on cable and satellite distribution in markets where it otherwise could not maintain a primary affiliation until 2014, when it began accepting subchannel-only affiliates through deals with Telemundo Station Group and Media General.
