1. Go to the page at Econsultancy.com and view the infographic (SEE ATTACHED) on the history of Tag Management https://econsultancy.com/blog/10306-the-history-of-tag-management-infographic (note: Tagman is now owned by https://www.ensighten.com/.) Also note that the infographic and article were published in 2011/2012 timeframe, and there may have been a few new developments in Tag Management since then.
2. Write one or two paragraphs discussion who (what industries, specifically) are using Tag Managers, and why they are needed, in general.
3. Do some research to find out how many Tag Management Platforms there are today. How many are there, and which ones are they? Do any have an advantage? For example, if Google and Adobe each have their own Tag Managers, is there any advantage that is built in by using a Tag Manager designed to integrate with the Analytics Stack that an enterprise is using, or does it not matter? What do you think?
