While TPG held the Internet providers as an unnamed collective unit, they somewhat maintained independence from each other despite sharing resources. TPG then expanded the unit with its purchase of Houston-based enTouch Systems on September 18, 2020, for an undisclosed sum.[5][6] Less than two months later, Stonepeak Infrastructure Partners announced on November 1 that it would purchase the unit, by then named Astound after a previous name used by Wave in San Francisco, from TPG for $3.6 billion along with $4.5 billion in debt through a leveraged buyout;[6][7][8] TPG had explored selling Astound due to the increased demand for Internet bandwidth during the COVID-19 pandemic.[9] Astound's expansion continued with its purchase of San Luis Obispo-based Digital West on January 26, 2021, also for an undisclosed sum.[10]
