The Port Washington location of a Toronto-based company that develops and distributes entertainment content will close in June, according to a state regulatory filing.

The notice from Entertainment One posted Friday on the state Labor Department’s website says 65 workers will be affected. The layoffs are scheduled to begin Dec. 31 and continue until the business closes.

The closing is a result of declining revenue from the distribution of recorded entertainment such as CDs and DVDs, a representative for the parent company said Tuesday.

“This comes with a change in physical distribution and consumption patterns,” the representative said.

Entertainment One, which has several other U.S. locations and another half-dozen offices worldwide, specializes in the development, acquisition, production, financing, distribution and sales of entertainment content, its website says. Its digital distribution business includes gathering content for “partners” such as iTunes, Netflix, Amazon, Sony PlayStation and Xbox.

The state Worker Adjustment and Retraining Notification Act, or WARN, requires companies with at least 50 full-time employees to file a 90-day notice of a mass layoff or closing.
