NEW YORK — YouTube plans to produce a slate of original video programs to air on its website, as the Google-owned company seeks to retain its audience amid competition from the likes of Netflix, Hulu, and Facebook.

During a presentation at New York’s Javits Center on Thursday, YouTube boss Susan Wojcicki showcased some of the new programs, which she said were something that YouTube advertisers had been asking for.

The shows will feature big-name celebrities like Ryan Seacrest and comedian Kevin Hart, and will be available exclusively on YouTube’s free, advertiser-supported website, and not on the company’s subscription-based premium service, YouTube Red.
