Network World Reports an 11% Increase in Network Industry Revenues

SOUTHBOROUGH, MA – APRIL 24, 2006 – Network World, Inc., the leading Network IT media company, this week published its annual guide to the 200 largest North American public network companies, ranking them by revenue, profits, earnings per employee and other measures. Overall results showed an industry on the upswing, with collective revenues climbing 11% to $919 billion, and profits growing 16%. A record 70% of the companies on the list were profitable, an impressive increase of 5% over last year.

"The picture gets even brighter when you narrow the view to the industry's echelon," said John Dix, Network World editor in chief. "The top 63 NW200 companies have sales of $1 billion or more and more than half of these companies saw sales climb an impressive 10% or more."

Consolidation has created enormous shifts in the industry, the list reveals. For instance, the new AT&T, built from the merger of AT&T and SBC, unseated IBM from the No. 1 spot, a position that IBM had held for years. The ten companies topping the list were: AT&T (NYSE:T), IBM (NYSE:IBM), HP (NYSE:HP), Verizon (NYSE:VZ), Dell (NASDAQ:DELL), Time Warner (NYSE:TWX), Microsoft (NASDAQ:MSFT), Intel (NASDAQ:INTC), Motorola (NYSE: MOT) and Sprint Nextel (NYSE:S).

The NW200 issue also highlights 10 Start-ups to Watch, small companies with bright futures that may some day join the ranks of the NW200. Drawing from a field of about 100 candidates, Network World editors handpicked these companies based on the strength of their technology, their management team and the depth of their financial backing. Network World's 10 Start-ups to Watch for 2006, and their products, are:
