How has adtech evolved in the past 20 years?

Advertising technology has come a long way since 2000. In the early 2000s, many advertisements were still being placed in traditional media, such as newspapers, magazines, and television. However, the rise of the internet and digital media has greatly changed the advertising industry.

One of the biggest developments in advertising technology has been the rise of online advertising. This has allowed companies to target their advertisements to specific demographics and to track the effectiveness of their ads in real-time. Online advertising includes methods such as pay-per-click advertising, search engine optimization, and social media advertising.

Another significant development in advertising technology has been the rise of mobile devices. The widespread adoption of smartphones has opened up new opportunities for advertisers to reach consumers. This has led to the growth of mobile advertising, which includes methods such as mobile search ads, in-app ads, and location-based ads.

In recent years, there has also been a rise in the use of artificial intelligence (AI) in advertising. AI allows advertisers to personalize their ads for individual consumers and to automate many advertising tasks. This has made advertising more efficient and effective, but it has also raised concerns about privacy and the potential for AI to be used for nefarious purposes.

Advances in digital technology have allowed advertisers to reach consumers in new and innovative ways, but these developments have also raised important ethical questions. As the advertising industry continues to evolve, it will be important to balance the benefits of new technology with the need to protect consumers' privacy and interests
