In 2000 LightingUniverse.com went live with a catalog of around 5,000 products. Two years later ATG Stores launched FixtureUniverse.com, targeting plumbing fixtures and decorative bath products. In 2003 Allied Trade Group, Inc. was formed as the parent company of Lighting Universe and Fixture Universe with the goal to grow into a full line home furnishings supplier.

Lowe's Home Improvement acquired ATG on December 29, 2011 with the intention of expanding the product variety available to Lowe's stores and Lowes.com while also bringing more traffic and credibility to ATG as an online e-tailer. This initiated the closing of the ATG retail showrooms in Washington state and allowed for Lowe's customers to purchase ATG items in-store for pickup.
