Gilbert-based PBT Telecom and PBT Communications, which provide phone, cable and Internet service in the Midlands, will take on the Comporium name Monday.
Rock Hill-based Comporium bought then-family owned PBT in 2004. PBT was founded in 1903 as Pond Branch Telephone.
PBT's 20,000 customers in Lexington, Saluda, Edgefield, Orangeburg, Calhoun and Aiken counties will see no changes except for a new name on their bills and at PBT's four offices, said Glenn Martin, general manager of what now will be known as Comporium Midlands division.
There also will be no change for PBT's 100 employees except for the new corporate name, he said.
Comporium, which also serves York and Lancaster counties, said it ranks behind only AT&T in the number of phone lines in South Carolina. In 2001, Rock Hill Telephone and its affiliates changed their name to Comporium, a combination of the words communications and emporium.
Comporium also offers security service and is a licensed provider of AT&T's wireless service.
