There are now close to 100 million .com domains in the world. To date, 98 million .com domain names have been registered and more added each day. At the current rate, the 100 million mark should be reached by the end of the year.
Pingdom,
based on Registrar Stats data, has put up a small chart displaying the number of .com domains through the years. .com remains the most popular TLD, yet its growth has slowed down somewhat in recent years.
That's to be expected since, precisely because there are so many domains already registered, people are looking at alternatives to get the name they want.
Still, there were only 21 million .com domains registered by 2000 and 61 million five years later.
Overall, according to another data source, there are now
500 million websites online at this point and the number is still growing strong.
