Verizon said its 10-day FiOS Free On Demand Spring Marathon set a viewership record, pulling in 1.8 million unique users, up 16% from last year’s 1.5 million.

Running April 3-13, Verizon’s fourth annual VOD-fest drew more than 1 million transactions each day.

On an on-demand basis, X-Men: Days of Future Past was the most-watched movie during the event, ABC was the most-watched network (it had six of the top 25 shows, led by Scandal and Modern Family), and HBO’s Game of Thrones was the most-viewed series as customers binged ahead of the season five premiere on April 12.

In a blog post, Verizon said week-to-week premium network transactions rose by 31%, while non-premium networks saw a 10% bump.

Verizon ended 2014 with 5.64 million FiOS video subs.

Comcast’s similar “Watchathon Week,” which ran from April 6-12 and factored in cross-platform TV Everywhere viewing, also set usage records.
