'Die Sendung' (the program/shipment) is the noun related to the verb 'senden' (to send/broadcast). The ending '-ung' turns the verb into a noun that describes either the process or the result of sending.
Ich muss dir noch ein Paket senden.
I still have to send you a package.
The two main meanings can be easily distinguished by context. Words like 'Fernsehen' (television), 'Radio' (radio), 'live' (live), or 'Moderator' (presenter/host) point to a program. Words like 'Post' (mail), 'Paket' (package), 'ankommen' (to arrive), or 'Adresse' (address) refer to a delivery.
Hast du gestern Abend die politische Sendung gesehen?
Did you see the political program last night?
When a program is meant, 'Sendung' (program) is often combined with verbs such as 'sehen' (to see/watch), 'schauen' (to watch), 'hören' (to listen to), 'aufnehmen' (to record), or 'verpassen' (to miss). People also speak of a 'Live-Sendung' (live broadcast).
Ich habe die letzte Folge der Sendung leider verpasst.
Unfortunately, I missed the last episode of the program.
In the context of a delivery, 'Sendung' (shipment) is often used with verbs such as 'erwarten' (to expect), 'erhalten' (to receive), 'aufgeben' (to send/drop off), or 'verfolgen' (to track).

On television or radio, both Programm and Sendung can refer to broadcast content. Programm usually means the planned selection or sequence of several items, while Sendung usually refers to a single broadcast. Use Sendung for the individual item and Programm for the overview.
