A new year — and a new U.S. subscription streaming service that snagged the No. 1 spot on our most in-demand digital chart for the US. “Titans” is a live-action superhero series — based on the DC Comics team of the same name — generated more than 34 million average daily Demand Expressions to take the No. 1 spot from perennial chart-topper “Stranger Things,” from Netflix, which finished the week at No. 2, with just a few thousand fewer average daily Demand Expressions. “Titans” had spent the two previous weeks at No. 2. Netflix may have ceded the No. 1 spot on the digital originals chart to a newcomer, but there’s a silver lining: The U.S. streaming kingpin holds international distribution rights to “Titans” and will be releasing the show outside the United States on Jan. 11.
