The Internet continues to pummel newspapers, which are losing advertisers to online media and failing to earn enough from their own digital operations to cover operating costs. Internet sites have proliferated, but a handful — led by Google — have corralled the vast majority of visitors and income. Privacy advocates are increasingly concerned about online companies collecting vast amounts of personal information about users. The federal government is attempting to figure out how to thwart cyber attacks by criminals, terrorists and unfriendly nations. The proposed Cyber Intelligence Sharing and Protection Act (CISPA) would allow businesses and government to share cyberthreat information without violating antitrust and privacy laws, but President Obama has threatened to veto the measure, saying it would violate consumer privacy. Meanwhile, debate rages over how to protect intellectual property in the digital age.
