15WHIH World News
This is a cool one. The WHIH World News is a news network present throughout pretty much every MCU property. You often catch quick glimpses of them reporting on whatever the current major event is. But Marvel didn't stop there. There was also a web series called WHIH Newsfront that
slowly built up to the events of Captain America: Civil War.
The series featured interviews with prominent MCU players like Scott Lang, Darren Cross, and President Ellis, all portrayed by their respective actors from the films. These segments added a real world gravitas, first to the threat in Ant-Man, then to the mounting tension surrounding the Avengers' ability to act without governmental restriction.
The network is just another great subtle way Marvel reminds us that it's all connected.
