LOS ANGELES — For the first time, Univision will make its popular Spanish-language novelas, variety shows and reality series available online, through Internet television provider Hulu.

The deal represents a milestone for Univision, the fifth-largest television network in the U.S., whose popular programming dominates the Spanish-language market.

Starting later this year, Univision said, it will make some of its prime-time shows available on the free, ad-supported Hulu.com site a day after an episode’s initial airing. A more extensive collection of the current season’s shows and past series can be found on Hulu Plus, the subscription service that charges $7.99 a month.
