Our most valued cultural institutions, Keen warns—our professional newspapers, magazines, music, and movies—are being overtaken by an avalanche of amateur, user-generated free content. Advertising revenue is being siphoned off by free classified ads on sites like Craigslist; television networks are under attack from free user-generated programming on YouTube and the like; file-sharing and digital piracy have devastated the multibillion-dollar music business and threaten to undermine our movie industry. When anonymous bloggers and videographers, unconstrained by professional standards or editorial filters, can alter the public debate and manipulate public opinion, truth becomes a commodity to be bought, sold, packaged, and reinvented. The very anonymity that the Web 2. While no Luddite—Keen pioneered several Internet startups himself—he urges us to consider the consequences of blindly supporting a culture that endorses plagiarism and piracy and that fundamentally weakens traditional media and creative institutions.

An amateur radio operator is someone who uses equipment at an amateur radio station to engage in two-way personal communications with other amateur operators on radio frequencies assigned to the amateur radio service. Amateur radio operators have been granted an amateur radio license by a governmental regulatory authority after passing an examination on applicable regulations, electronics, radio theory, and radio operation. As a component of their license, amateur radio operators are assigned a call sign that they use to identify themselves during communication.

Licenses to operate amateur stations for personal use are granted to individuals of any age once they demonstrate an understanding of both pertinent FCC regulations and knowledge of radio station operation and safety considerations. Applicants as young as five years old have passed examinations and were granted licenses. Operator licenses are divided into different classes, each of which corresponds to an increasing degree of knowledge and corresponding privileges. Over the years, the details of the classes have changed significantly, leading to the current system of three open classes and three grandfathered but closed to new applicants classes. Amateur radio licenses in the United States are issued and renewed by the Federal Communications Commission without charge, although the private individuals who administer the examinations may recoup their expenses by charging a fee.
