NEW YORK — One US Supreme Court justice referred to Netflix as “Netflick.” Another seemed not to know that HBO is a cable channel. A third appeared to think most software coding could be tossed off in a mere weekend. These and other apparent gaffes by the justices during oral arguments have became a source of bemused derision, as tech aficionados, legal experts and others have taken to social media, blogs, YouTube and other outlets to proclaim the justices black-robed techno-fogeys. Meanwhile, Netflix is raising its Internet video prices by $1 per month for new customers and giving its current US subscribers a two-year break from the higher rates. The changes mean anyone signing up for Netflix's video subscription service beginning Friday will pay $9 per month for in the US. The old price of $8 per month will continue until May 2016 for Netflix's existing 36 million US subscribers. — Reuters
