Terms of the deal have not been disclosed.
TDS Broadband is operated by Madison-based TDS Telecommunications Corp., a subsidiary of Telephone and Data Systems, a publicly traded company in Chicago.
The acquisition only involves broadband services but TDS also offers cable TV to the St. George market, spokeswoman DeAnne Boegli said.
She said St. George is a rapidly growing area and is a "very important market" for TDS.
