Telecommunications companies use various technologies to transmit information globally. Some of the largest companies in the telecommunications sector provide telephone and wireless services, as well as internet data and video communications.
The telecommunications sector is changing rapidly. Traditional technologies such as wireline (also known as landline or fixed-line) telephone, radio, and television once dominated the telecommunications universe. But wireless mobile and internet technology are quickly becoming the new norm.
Below are the 10 biggest telecommunications companies by 12-month trailing (TTM) revenue. This list is limited to companies that are publicly traded in the U.S. or Canada, either directly or through ADRs. Some companies outside the U.S. report profits semi-annually instead of quarterly, so the 12-month trailing data may be older than it is for companies that report quarterly.
