General Telephone Company of the Northwest, Inc. was founded in 1964 and later became GTE Northwest, Incorporated. GTE Northwest originally served Idaho, Montana, Oregon, Washington.
In 1993, GTE acquired Continental Telephone (ConTel); as a result, ConTel operations in Oregon, Washington, and Idaho were merged into GTE Northwest. In 1994, GTE sold ConTel of Idaho to Citizens Communications (which later became Frontier Communications). In 1995, GTE sold operations in Montana to Citizens Communications, and absorbed ConTel of Oregon into GTE's existing Oregon operations.
In 2000, Bell Atlantic acquired GTE, forming Verizon. As a result, GTE Northwest was renamed Verizon Northwest, Inc. It continued to provide local telephone service to former GTE regions and some ConTel regions in Idaho, Washington, and Oregon.
Verizon Northwest, along with several other Verizon wireline operating companies, were acquired by Frontier Communications on July 1, 2010. The company's name was changed to Frontier Communications Northwest, Inc.
In May 2019, WaveDivision Capital announced that it would buy Frontier Communications Northwest operations for nearly $1.4 billion as part of a new service. WaveDivision Capital (“WDC”) was founded in 2003 by broadband entrepreneur Steven Weed. It is a private investment firm focused on the broadband industry, and its stated goal is “to bring better internet connections to more homes and businesses throughout North America”. Weed was the CEO of Wave Broadband until 2018, when the company was sold and he departed. Despite having similar names and key players WaveDivision Capital and Wave Broadband are not related. WaveDivision Capital formed Northwest Fiber to acquire the Frontier Communications Northwest operations, which was approved by federal and state regulators on February 19, 2020, with the new service receiving the name of "Ziply Fiber". Frontier Communications Northwest division ceased operations on April 30, 2020, and was replaced the following day by Ziply Fiber. As of 2020, the company has almost 1000 employees and serves over 500,000 customers.
