Quanta reentered the U.S. communications infrastructure services market in 2017. In 2018 we added 13 new customers, which more than doubled our U.S. customer count and contributed to a 20% increase in overall communications infrastructure services backlog. Those achievements validate our focus on selecting the right projects and executing well for our customers. While our focus is to grow our operations organically, we opportunistically acquired two quality companies in 2018 to strategically bolster key regional markets.
We continued to reestablish our U.S. operations and expand our presence in 2018. With a solid roster of new clients and strong backlog in place, we believe we have the momentum to grow our communications operations into a $1 billion annual revenue business in the medium-term. Our solid execution is allowing us to gain traction and more deeply collaborate with customers.
