uTorrent's parent company BitTorrent Inc. just announced that the BitTorrent Mainline client and uTorrent combined have hit the milestone of 100 million monthly users. On an average day 20 million users from over 220 countries fire up one of the two BitTorrent clients. If that's not enough, the company also reports that 400,000 new clients are downloaded every day.

uTorrent for Windows saw its first public release in September 2005 and soon became the most widely used BitTorrent application. The potential of the minimalistic client was soon picked up by BitTorrent Inc. who bought it in December 2006.

In the years that followed the original BitTorrent mainline client was gradually transformed into a rebranded version of uTorrent, and today BitTorrent Inc. announced that both clients combined now have more than 100 million active users a month. Users literally come from all over the world, with 20 million active daily users from over 220 countries.

“This is an exciting day for our team. Our vision is to build a complete technology ecosystem comprised of software, content and devices, designed to connect modern content creators with a massive digital audience,” BitTorrent CEO Eric Klinker said. “This milestone highlights the size of our user base and the power of our software.”

BitTorrent Inc.’s acquisition of uTorrent is without doubt the best decision the company has ever made. Where other projects such as the “movie store” and CDN-services failed miserably, uTorrent’s popularity kept on growing.

The irony is that the company which founded one of the most innovative technologies on the web in the last ten years, has not managed to build a new business model around it. Perhaps the BitTorrent powered movie store and CDN were ahead of its time, but the fact is that the company now relies on a toolbar to pay the salaries of its employees.

While there is no shame in relying on toolbars to keep million of BitTorrent users satisfied with an entirely free experience, we can only assume that the company had a greater plan in mind when it was founded back in 2004. That said, toolbars do bring in some serious money.

In addition to the millions of daily active users, the BitTorrent Mainline and uTorrent client are downloaded by 400,000 people a day according to BitTorrent Inc. An unknown percentage of these new downloads also choose to install the toolbar, which is good for millions of dollars in revenue a year.

This stable stream of revenue ensures that BitTorrent Inc. can continue the development of uTorrent in the future, and that’s a welcome message to at least 100 million BitTorrent users. TorrentFreak congratulates BitTorrent for reaching this impressible milestone, and we’re eager to see how far this number can increase in the future.
