Comcast is expanding the OTT content available on its X1 boxes with the initial rollout/integration of iHeartRadio, the free digital music, podcasting and live streaming radio service.

As part of the integration, iHeartRadio content will also be searchable with the X1 voice remote. X1 subs will also be able to browse and select stations integrated throughout related sections of Comcast’s Xfinity On Demand service. For example, X1 subs might find featured country music stations within the music section of the MSO’s VOD service during the week of the Country Music Awards, they said.

Comcast is starting to roll out the iHeartRadio app to compatible X1 boxes today, and expects to complete the rollout in the coming weeks. X1 subs can listen to iHeartRadio without registering, but can also use their iHeartRadio accounts for a more personalized experience.

iHeartRadio content will be delivered to X1 boxes via public internet connections, so that data will be subject to Comcast’s usage-based broadband policy.

Other MVPDs to integrate iHeartRadio at the set-top include AT&T (for U-verse) and Layer3 TV.

The addition also expands the number of OTT apps to be woven into X1. Others include YouTube, Pandora, and Netflix, some casual games, with Sling TV among those that are on deck.

In its latest effort to blend pay TV with OTT, Layer3 TV said it has integrated the iHeartRadio digital music, podcasting and live streaming radio service on all its set-top boxes.

iHeartRadio is the first live streaming radio app offered on Layer3 TV’s platform, which has already integrated Facebook and YouTube, with more apps to come.

The iHeartRadio app, accessible via the Layer3 TV user interface, lets subs search for and playback radio stations based on genre, location or keyword, pick from thousands of live radio stations, including certain local stations, create custom artist radio stations, and receive personal recommendations based on listening habits, location and musical preference.

Layer3 TV has launched service in Chicago, Los Angeles, Dallas, and Longmont, Colo., and has confirmed plans to enter the New York market.

“Layer3 TV customers expect us to deliver them the best television experience, but now they can also listen to all their favorite artists, music and local radio personalities thanks to Layer3 TV and iHeartRadio’s innovative integration,” Lindsay Gardner, Layer3 TV’s chief content officer, said in a statement. “On top of over 250 of the top television channels, iHeartRadio brings its seemingly unlimited music offerings into every Layer3 TV customer’s living room.”

“It’s our goal to make sure listeners have access to iHeartRadio everywhere they are, 24/7. This integration is yet another example of giving our listeners access to all their favorite music, radio personalities and stations on the products and services they use most,” added Jessica Jerrick, EVP of business development and partnerships at iHeartMedia.

Other U.S. MVPDs have likewise begun to integrate OTT music services on their pay TV platforms. Among examples, AT&T U-verse also offers iHeartRadio, and Dish Network and Comcast (for X1) have tied in Pandora.

Investigation Discovery will team with veteran TV news personality Barbara Walters to create a new series focused on infamous political scandals.

The series, Barbara Walters Presents American Scandals, will premiere Nov. 2, Discovery Group president Henry Schleiff announced during the network's Television Critics Association Tour session Thursday.

“Journalist. Author. Television personality. In our lifetime, there is no other name more associated with headlines and stories that mesmerized readers and viewers than Barbara Walters. Indeed, only the incomparable Barbara Walters could deliver these original interviews and get the subjects to speak to her,” he said.

Schleiff also announced that the network will partner with iHeartRadio to develop a weekly news-driven radio series looking at headline-making cases.

The network will also team with the Southern Poverty Law Center for a new series And Justice For All focused on the diversity group’s case files, according to Schleiff.

iHeartRadio has become the first live streaming radio app to launch on U-verse TV, AT&T’s IP-delivered pay TV platform.

The app, which requires users to have U-verse high-speed Internet service, is accessible on U-verse channel 532/1532 and allows users to search for radio stations based on genre, location or keyword; select from thousands of live radio stations; receive personalized recommendations based on listening habits, location and musical preferences; and access a list of saved or recently listened-to stations.

AT&T and iHeartMedia said they will add new features to the app later this year, including custom stations created from a library of more than 20 million songs and 800,000 artists, as well as song lyrics, artist biographies, stations "Perfect For" any mood or activity, and thousands of podcasts.

AT&T U-verse TV currently supports more than 30 apps, including music-focused apps such as Country Deep, Stingray Music, Karaoke TV and U-verse Jukebox.

“Personalization is one of the key features of AT&T U-verse TV, so a highly-customizable app like iHeartRadio is a natural fit,” said GW Shaw, vice president of U-verse and video products at AT&T, in a statement. “We’re excited to bring iHeartRadio and its extensive offerings to our U-verse customers.”

Integrating music apps at the set-top level has become an increasingly common play for U.S. MVPDs.

Comcast, for example, offers access to Pandora via its IP-capable X1 platform. Dish Network, meanwhile, announced in January that its Hopper and Joey boxes would add support for several third-party OTT music offerings, including Pandora, iHeartRadio and TuneIn, as well as to Vevo, the music video streaming service. Dish is also working on Dish Music, an app that will “discover” Hopper and Joey devices on the home network, allow customers tovselect from multiple music sources and independently control what music is being piped into the house. 

NBCUniversal and Jeep have launched a multiplatform social media campaign across four NBCU networks to cross-promote NBC’s March 29 telecast of the second annual IHeartRadio Music Awards, which includes a new Jeep-sponsored award, and the availability of the 2015 Jeep Renegade.

Starting yesterday (Feb. 8) through March 29, Bravo, E!, Syfy and NBC are each running network-specific spots soliciting viewers to post photos of their adventurous lives on Twitter and Instagram with the hashtag #RenegadeLifeContest; submissions will be featured on the networks’ websites, with winning photos to be featured in future campaign spots.

Additionally, three participating viewers will be selected to attend the IHeartRadio Music Awards in Los Angeles, where they will also be part of filming a custom, NBCUniversal-produced Jeep Renegade spot that will air during the March 29th broadcast. The three also will receive a 2015 Jeep Renegade.

Bravo has already placed its call to action on its website, directing viewers to tune in during Real Housewives of Atlanta on Sunday nights to see if their photos have been chosen.

The campaign also spotlights a new “Renegade” award, sponsored by Jeep, to recognize artists who “defy convention and let their instincts rule”; the nominees are Brantley Gilbert, Charli XCX, Hozier, Iggy Azalea and Meghan Trainor.

“We know that our Millennial audience looks to multiple engagement platforms … to discover what's new and share this content,” said Kim Adams House, Head of Jeep Brand Advertising, FCA US. “Through this partnership, we’re able to offer this group the opportunity to learn more about our vehicle through channels in which they are familiar. NBCUniversal's portfolio of networks allows us to authentically interact with some of its most socially engaged audiences."
