Top Players in the Global Advertising Market

The global advertising market reached a value of US$ 647 Billion in 2020. At present, there is a rise in the trend of digital out-of-home (OOH) advertising on account of its ability to create immersive, memorable, and interactive campaigns in a cost-effective manner. This, coupled with the growing utilization of smartphones and rising penetration of high-speed internet, is propelling leading advertisers to fund mobile advertising as it is an efficient way of targeting specific groups of mobile users. Furthermore, a consistent increase in the expenditure on media and entertainment, along with the growing investment in digital advertising, is offering a lucrative growth opportunity to industry players. Looking forward, IMARC group expects the market to grow at a CAGR of 5.2% during the forecast period (2021-2026).
