The biggest advertising trend that 2021 will reveal is probably the explosion of programmatic ads via artificial intelligence (AI) to automate ad purchases. This will allow brands to target even more specific audiences.
Also, as the range of channels used for reaching customers grows, it is becoming increasingly difficult to manage. Managing programmatic platforms through AI solves this problem as they use targeting signals and real-time adaptation for individual ads or campaigns via any given channel.
Across this type of advertising, exciting trends such as the use of voice search and voice commands for commercial purposes, the introduction of blockchain or 5G network are likely to experience a boom in 2021.
