Thousands of Hollywood TV and movie screenwriters have begun a mass walkout after planned discussions over wages broke down.

Late-night programs including the Tonight Show and The Late Show will be the first to shut down, with incoming films and shows expecting delays.

US correspondent Dan Mitchinson says the last high-profile writers' strike was over 15 years ago- and the media landscape has expanded since.

Dan Mitchinson says viewers have streaming services full of content to choose from, and they'll gravitate to those platforms if the writers' strike puts new entertainment on hold.
