Usage of Google Tag Manager on the Web

It's always interesting to know how many people are using a technology, isn't it? Yes, it is. Even though I have been using different Tag Management systems from a quiet an amount of time, I am really not sure how many people/businesses are using a particular Tag Management solution.
I have been searching about this on the internet and came to know about a cool website called builtwith.com which is exactly what I was looking for. It gives out the number of websites which uses a particular technology. So as for the Google Tag Manger goes check out the below infographic which show cases the number of Top 10K, 100K and Million websites which uses Google Tag Manager and the trend over the time.

Surely, Google Tag Manager is being adopted quickly and as expected the 3rd tier of websites are the quickest to adopt it. Tier one websites are slowly making the transition to GTM. It can be due to the presence of Enterprise level Tag Management solutions like Ensighten, Tealium etc.

The builtwith website also gives an approximate number of total websites on web which use Google Tag Manager. It comes around 616,000+ which is huge but a long way to go though.
