In this menu, the user selects the channels to which he wants to distribute the spot. TV channels, in the case of video, or Radio channels, in the case of audio.
The availability date is the date on which the channel or channels to which the distribution was made are able to view/listen to the spot. This date is, by default, the date of the day we are on. We advise you not to change the availability date, which has nothing to do with the first exhibition date. But in any case it can be changed, taking into account that it should be always before the date of the first airing, so that the channels have time to view the spot and validate that everything is ok (never before a week).
