Battle Lines Drawn Over Spyware
A contentious debate is forming around the issues of spyware - software that can track which websites a computer user visits. Marketers implant the software on computers to better tailor their online advertising, and they argue that the practice helps consumers by targeting their interests. But many individuals find spyware invasive. And many companies that rely on Web sites to reach many of their customers, have filed suits against spyware makers, arguing that they are violating copyright and trademark laws by popping up ads when people visit the plaintiffs' sites.
