What is the common duration for commercial spots on television and radio?

In the context of commercial spots on television and radio, the common durations are 15, 30, and 60 seconds. This standardization helps advertisers communicate their messages effectively within a timeframe that is both manageable for viewers and listeners and economically viable for media outlets.

Fifteen-second spots are popular for quick messages, often used in high-frequency campaigns or radio where listening sessions may be short. Thirty-second spots are the most widely used duration, striking a balance between providing enough time to convey a message without losing audience attention. Sixty-second spots allow for more in-depth storytelling, which can be particularly effective for campaigns that need to establish a brand narrative or convey a more detailed message.

The other durations listed in the choices are less common in regular scheduling or may be more niche. Therefore, the frequency and standardization of 15, 30, and 60 seconds across different platforms make these durations the most typical for commercial advertising.
