The .com top-level field has dominated the Internet pretty much from the start, and that’s still the case. But how strong is this dominance? After all, there are now approximately 200 million registered field names, and less than half of those are .coms.
To find out what the current situation looks like for actual, well loved websites, we’ve looked at this from two different perspectives:
This article will show you the distribution of top-level domains (TLDs) among these top websites to show you how widely used .com is today, and how the additional top-level domains are doing by evaluation.
We get two very different pictures depending on which set of websites we look at, although the pattern is similar.
But before we proceed, let’s get two definitions out of the way for those of you not fluent in field speak:
Now that that has been cleared up, let’s get to the charts.
So what does the TLD distribution look like for the top 10k websites in the world? Here it is, as a pie chart for your viewing pleasure. (Pacman, anyone?)

In the chart above, we only included TLDs with 1% or more of the worldwide top 10k. The rest were lumped together in the “additional” category.
As you can see .com has a very dominant spot, which was to be expected. Since ccTLDs tend to be public-specific, it will be hard for them to reach the very top worldwide.
A few points of interest for the worldwide top 10k sites:
So what does the situation look like if we only study websites that are well loved in the United States?
We had a feeling that the difference between the worldwide and the US-only perspectives would be huge, and we were right. If the worldwide chart showed .com as a Pacman ready to bite, in this one Pacman is gulping down the additional TLDs like an afternoon snack.

Again, we only included TLDs that had 1% or more of the top 10k websites. The rest were place in the “additional” category.
A few points of interest:
What it tells us is that whichever way you slice it, .com is still king.
Perhaps we are all, and Americans in particular, by now so schooled to seeing and using .com domains for top websites that additional TLDs may be seen with some ingrained level of touch.
Maybe something to keep in mind when you’re registering a field for your next startup.
