The metaverse as a concept can be complex to understand. Frost & Sullivan categorizes the metaverse as an interconnected network of persistent 3D worlds and simulations where end users, represented by virtual avatars, are enabled with a sense of social presence and spatial awareness and participate in an extensive virtual economy. This study discusses growth opportunities for digital advertising in the metaverse as well as the different challenges and emerging trends related to the adoption of immersive experiences for marketing purposes. As the metaverse is changing how users interact with brands and creating an abundance of innovative opportunities to advertise, a wide range of companies are developing metaverse strategies and deploying diverse use cases. Both the fashion and retail industries have been early adopters of the metaverse, primarily due to the existing synergies between the metaverse and their product portfolios. However, a growing number of other industries are starting to show increasing interest in advertising in 3D worlds. Frost & Sullivan believes that the expected growth of the metaverse will impact the way enterprises establish their business priorities for the next decade. As some consumers gradually change their primary means of consumption and adopt new 3D worlds and leave aside traditional channels, such as TV or Internet browsers, companies will increase their efforts to build their brand presence in these evolving immersive worlds. The metaverse is forging a new path for digital advertising. It unfolds a new wave of monetization opportunities not only for vendors interested in attracting new customers and boosting their sales but also for metaverse builders and tech companies that will enable the transition to immersive worlds as well as media, public relations, and marketing agencies that will vet the opportunities and develop innovative advertising strategies. Frost & Sullivan believes the metaverse has the potential to become the next-generation channel for advertising, communications, brand exposition, and customer engagement.
