    VoIP Gains Ground

    Residential voice over Internet Protocol (VoIP) telephone subscribers in the United States shot from 150,000 at the end of 2003 to more than 2 million in March 2005.

    Preliminary findings from TeleGeography's latest research show that total U.S. subscribers should exceed 4.1 million by the end of 2005, generating more than $1 billion in gross revenues for the year.

    Vonage, which entered the market early but does not own a communications network, is the largest provider of home VoIP service. Cable companies are close on the heels of Vonage because they possess a huge installed base of broadband customers through connectivity to millions of homes.

    TeleGeography predicts that by the end of 2005, Cablevision, Comcast and Time Warner Cable together will have 2 million subscribers, nearly half of the total residential VoIP market.

    Online Journals

    Only about 9 percent of Internet users say they've created a Weblog, according to the Pew Internet and American Life Project, which tracked the percentage of U.S. Internet users who read blogs from 2003 to 2005.

  • March 2003 -- 11 percent

  • February 2004 -- 17 percent

  • November 2004 -- 27 percent

  • March 2005 -- 25 percent

    Security Breach

    Approximately 45 percent of IT decision-makers said they could lose their jobs over Internet security breaches that result in lost or stolen intellectual property, according to Websense's 2005 Stress of Security Survey, which also reported that 65 percent of IT decision-makers said spyware caused security problems for their companies in the past year.

    Lost Productivity

    Internet misuse in the workplace costs American corporations more than $178 billion annually in lost productivity, according to Websense. That translates into a loss of more than $5,000 per employee per year.

    Additionally, according to Websense, more than 68 million U.S. employees currently access the Web at work.
