Two months after barring advertisements in which Jessica Simpson and William Shatner tout a satellite TV company’s high-definition service, a federal judge has permitted a similar endorsement by Christopher Lloyd reprising his Doc Brown role from “Back to the Future.”

Southern District of New York Judge Laura Taylor Swain last week, in Time Warner Cable Inc. v. DIRECTV Inc., 06 Civ. 14245, rebuffed an attempt by Time Warner Cable to block the DIRECTV commercial claiming that its high-definition service would be available “in the future” on more channels than its competitor.
