Verizon Wireless said that it has won a permanent injunction against a company it accused of sending text message spam, a significant step in keeping the unsolicited messages off cell phones.

In the judgment, Specialized Programming and Marketing and its owner, Charles Henderson, are prohibited from sending text message spam to Verizon Wireless customers. They are also required to pay damages in excess of $200,000. Verizon Wireless filed the suit after nearly 100,000 text messages were sent to Verizon Wireless customers offering them a prize vacation for a cruise to the Bahamas.
