Pubblicità vs. spot
While both terms relate to marketing on television or radio, pubblicità is the general term for advertising or the commercial break, whereas spot refers to a single, distinct commercial clip.
Pubblicità
A2This word refers to the broad concept of advertising, the industry as a whole, or the commercial break acting as a collective group of ads. It is generally used as a singular, uncountable noun, similar to how English speakers use the word advertising.
Non cambiare canale, c'è la pubblicità.
(Don't change the channel, the commercials are on.)
Lavora nel mondo della pubblicità da dieci anni.
(He has been working in the world of advertising for ten years.)
Odio quando il film è interrotto da troppa pubblicità.
(I hate when the movie is interrupted by too much advertising.)
Faremo molta pubblicità per questo evento.
(We will do a lot of publicity for this event.)
La pubblicità sui social media è efficace.
(Advertising on social media is effective.)
Spot
B1Borrowed from English, this term refers to a specific, piece of advertising content. It describes a single unit of advertisement (a 30-second clip) rather than the general concept. It is a countable noun.
Hai visto lo spot per la nuova macchina?
(Did you see the commercial for the new car?)
Il loro spot dura solo quindici secondi.
(Their commercial lasts only fifteen seconds.)
Hanno girato uno spot divertente con un attore famoso.
(They filmed a funny commercial with a famous actor.)

(That is my favorite commercial of this year.)

(They broadcast the same commercial three times in a row.)
Summary
Use pubblicità when referring to the commercial break, the industry, or advertising in general. Use spot when discussing one specific video or audio advertisement.
