According to Facebook CEO Mark Zuckerberg, the social networking site will be mostly video in next five years.

"In five years, most of the Facebook will be video," Zuckerberg told a gathering at a community town hall meeting in California.

Responding to a question about why Facebook launched Messenger, he said that Messenger is a better experience and will get people faster responses from friends.

"Asking everyone in our community to install another app is a big ask. But Facebook thought it could provide a better, faster messaging product if it split off from its own app," he told the audience.

Zuckerberg also took questions from a froup of users, who were invite to the Facebook headquarters in Menlo Park, California in the US, TechCrunch reported.

Zuckerberg said that support for women entering science, technology, engineering and maths needs to start earlier so girls do not self select out, with regard to a query about what could be done to get more women into technology,

The issue of Facebook losing its "cool" was also raised but Zuckerberg maintained, "my goal was never to make Facebook cool. I want it to be a helpful service that just works".

Upon being asked as to why he wears the same shirt every day, he replied with a laugh, saying he has several such shirts.

"I wear the same gray t-shirt everyday because it speaks to how we think about our duty to the community here. I do not feel like I am doing my job if I spend any of my time on anything silly or frivolous in my life," he said.
