Adding a mobile video commercial (MVC) to marketing campaigns can provide several benefits: 1. MVCs can lead to viral spread as consumers are more likely to forward the video link to others via SMS or messaging apps. 2. Brand retention is higher with MVCs since the video stays on consumers' mobile devices and can be replayed, compared to other ad formats. 3. MVCs allow companies to add a call to action like collecting mobile numbers, enabling further engagement. 4. MVCs extend the life of campaigns as videos continue to be downloaded over a sustained period.
