Learn Italian: Oltre a offrire lo streaming, la piattaforma ha molti podcast. - Besides offering streaming, the platform has many podcasts.

In Italian, the connector oltre a (besides / in addition to) must be followed by a noun, a pronoun, or an infinitive verb. While English uses the -ing form after prepositions, Italian uses the infinitive. You cannot say oltre a offrendo.

Why is the plural of podcast just podcast without an "s" at the end?

Foreign loanwords in Italian, like podcast, computer, or film, are almost always invariable. This means their endings don't change in the plural. You know it is plural here because of the masculine plural adjective molti.

Why does streaming take the masculine article lo instead of il?

Even though it is an English word, it must follow Italian article rules. Because streaming starts with an "s" followed by a consonant ("t"), it requires the article lo.

Could I use inoltre instead of oltre a in this sentence?

Not with this sentence structure. Oltre a links directly to an infinitive or noun in the same sentence to mean "besides X". Inoltre means "furthermore" and introduces a new independent clause, as in: La piattaforma offre lo streaming. Inoltre, ha molti podcast.
