Univision Communications is relaunching all 72 Web and mobile sites for the Spanish-language broadcaster's TV and radio stations in the nation's 20 biggest Hispanic markets. The media company wants to improve user experience with easier navigation, more photo and video content offerings and increase social media functionality.

Sites have already relaunched in a number of top markets, including New York, Los Angeles and Miami, with additional efforts to follow in coming months in Chicago, Houston, Dallas, El Paso, San Antonio, Austin, Phoenix, San Francisco and San Diego, among other DMAs.

Like other major Spanish-language broadcasters, Univision has worked to stay abreast of rapidly changing media consumption habits among Latinos, reflecting similar trends in the population at large.

In October of last year, Univision and Time Warner Digital Cable launched a new on-demand service -- Lo Mejor on Demand -- in New York, Los Angeles, Dallas, San Antonio and San Diego, which has subsequently expanded to a number of other markets with large Latino populations.

TWC and Univision are also collaborating on three new products: Spanish-language VOD, StartOver, which allows viewers to restart a show already in progress, and LookBack, which lets them see a show after it has aired.

In June of this year, Univision bowed a new local media unit combining its radio, TV, and various interactive properties to offer an integrated platform to local advertisers in every market.
