Dear friend,
The "teaser campaigns" are conducted to promote a product. The company that sells the product launches the teaser campaign. Now against this backdrop, the brand name of the company automatically gets promoted. Where is the separate need to reveal the brand name?
For example, mobile phone manufacturing companies keep on sending the teasers of their upcoming phones. Samsung sends teasers of their product, and so does Oppo or Vivo, etc. Teasers are sent to the market to create interest in the minds of future customers. Based on the teasers, be it of a mobile phone or a car, the experts in the respective field start writing articles on it. This promotes the brand image of the company automatically.
In short, the objective of teasers is to create a sense of curiosity in the minds of the customers, whereas brand building activities are completely different. Both need to be seen differently.
Thanks,
