In the wake of a federal court ruling that tentatively endorsed its legality, Aereo will bring its $8-a-month service to Boston, Chicago, Philadelphia, Washington and 18 other markets in the U.S., as well as to New York's suburbs. For the past year, the service had been limited to New York City residents as the company fine-tuned its technology and awaited guidance on whether its unlicensed use of free, over-the-air broadcasts amounted to a copyright violation.A federal judge in New York ruled in July that the service doesn't appear to violate copyright law because individual subscribers are assigned their own, tiny antenna at Aereo's Brooklyn data center, making it analogous to the free signal a consumer would get with a regular antenna at home. Aereo spent the subsequent months selecting markets for expansion and renting space for new equipment in those cities. ___ Google executive gets look at NKoreans using Internet PYONGYANG, North Korea (AP) â¿¿ Students at North Korea's premier university showed Google's executive chairman Tuesday how they look for information online: they Google it. But surfing the Internet that way is the privilege of only a very few in North Korea, whose authoritarian government imposes strict limits on access to the Web. Google's Eric Schmidt got a first look at North Korea's limited Internet usage when an American delegation that he and former New Mexico Gov. Bill Richardson are leading visited a computer lab at Kim Il Sung University in Pyongyang. Other members of the delegation on the unusual four-day trip include Schmidt's daughter, Sophie, and Jared Cohen, director of the Google Ideas think tank. Schmidt, who is the highest-profile U.S. business executive to visit North Korea since leader Kim Jong Un came to power a year ago, has not spoken publicly about the reasons behind the journey to North Korea.
