Facebook will introduce a tool allowing users to clear their browsing history this year. Seperately, the company launched new advertising options for its premium video content.

The "clear history" option, will affect Facebook's ability to target advertisements, Chief Financial Officer David Wehner told an investment conference on Tuesday.

Facebook on Tuesday also launched new advertising options for its premium video content, hoping to help it make more money from its Facebook Watch feature.

The new program called Facebook Showcase allows advertisers to purchase ad spots in advance at a fixed cost. That feature, called In-Stream Reserve, will target audiences that are verified by audience measurement company Nielsen, which is also the industry standard for linear TV.

Every video is reviewed by a human before it is eligible to be part of Facebook Showcase, Erik Geisler, Facebook’s head of North America agency sales, said at a press event in New York on Tuesday.

Advertisers can now also purchase spots on premium content in the food and news categories, in addition to sports, entertainment and fashion and beauty, which had been available previously.

Facebook also introduced sponsorships, which allow advertisers to be the exclusive sponsor of a program for U.S. viewers.
