A 1988 law designed to protect the privacy of movie rentals in the age of Blockbuster Video is getting a fresh look from the Supreme Court. The justices heard arguments Wednesday in a case testing how the decades-old statute fits in the modern era of digital commerce.  A ruling by the justices could resolve a lower-court split over how a consumer qualifies for the law’s protections. Consumer advocates say the Video Privacy Protection Act of 1988 was broadly written to adapt to advances in technology and safeguard consumers’ personal information. The law's critics view it as a relic.
