Los Angeles: Alphabet's YouTube will launch a live TV service featuring US broadcast networks and cable channels to attract young fans of online videos to a pay television package, YouTube executives said on Tuesday.

The new offering, called YouTube TV, will compete with other servicesfighting to attract mobile-loving younger audiences who dropped pricier, traditional cable and satellite packages or never signed up in the first place.

YouTube TV will be delivered over the internet and debut in the coming months in the US at a cost of US$35 a month for six accounts, YouTube chief executive Susan Wojcicki told reporters at an event in Los Angeles.

YouTube TV subscribers will be able to watch original programming that appears on YouTube Red, a subscription service that includes movies and shows starring popular YouTube video creators.
