Exhibit 99.1

Capital Growth Systems Acquires 20/20 Technologies, Inc. and Magenta netLogic, Ltd.

SCHAUMBURG, Ill.--(BUSINESS WIRE)--Sept. 12, 2006--Capital Growth Systems, Inc. (OTCBB:CGSY.OB - News), announced today that it has completed the acquisition of 20/20 Technologies Inc., the holding company whose assets include total ownership of UK-based Magenta netLogic, Ltd., a global leader in circuit pricing and network optimization. The transaction represents part of the current CGSY strategic program of expansion to become a leading telecommunications services and solutions provider.

"The Magenta acquisition gives us a unique position with a communications supply chain management system, a global customer base and an experienced team in North America and Europe," stated Tom Hudson, CGSY chief executive officer. "Multi-national corporations, systems integrators and telecommunications companies have traditionally tried to execute on their networking requirements without the necessary keys to the supply chain in terms of information regarding circuit supply, availability and pricing. The Magenta intellectual property, technology and databases are a significant step toward providing that clarity, and we believe that will allow us to add significant value to our current and future customers. Magenta is already well established in a number of the largest global carrier and systems integrator operations."

Patrick Shutt, former CEO of 20/20 and current CGSY president, stated, "CGSY is engaged in an exciting period of growth. We believe the significant savings Magenta has already shown existing consulting clients give a formidable competitive edge to the company moving forward. We believe that the combination of this transaction and the strategic objectives of the company will give CGSY the framework to build the first Smart VNO capable of consistent, speedy and economic design and delivery of network solutions of any size or complexity with a global reach."

CGSY also recently announced the execution of a letter of intent to acquire Houston-based Global Capacity Group, Inc., an expanding connectivity provider.
