On Thursday, Facebook will hold a big event to unveil a “new look for the news feed.” Facebook’s news feed, the core part of the site’s experience, last received a major change in 2011.

According to a report at TechCrunch, Facebook will debut new content-specific news feeds, as well as tweak image sizes and add image-based ads.

“Multiple sources” confirm that Facebook is adding a few new ways to sort posts from your friends in your news feed. The first one of these new categories is a photo-only news feed that will take from both Facebook photos and Instagram photos. This will be the first major Instagram/Facebook integration since the photo-filtering app was purchased by Facebook last year.

Another content feed that will launch is for music, and will feature info from Spotify, Rdio, and others. You will also find info on nearby concerts, new albums, and a consolidation of all the posts from artist’s pages that you like. It’s possible that there could eventually be more of theses content-specific feeds for things like videos or apps.

Alongside the new photo feed comes a bigger focus on images in general – and yes that means within ads too. Facebook will reportedly unveil larger images throughout the news feed – in both organic posts from friends and in advertisements.

These changes will first affect the desktop news feed, and could later expand to mobile.

As always, we’ll be covering the event on Thursday. Check back with us to see what happens during the big reveal.
