Dive Brief:

• A handful of brands are experimenting with Instagram's carousel ads, which were introduced last month. 
• Old Navy, Samsung, Banana Republic, and Showtime are among the first brands to test out the ads that allow for four rotating photos and active links. 
• Old Navy, for example, is using the carousel ads to promote its Baja summer line with a "day-in-the-life" photo series that highlights items in real-life settings. 

Dive Insight: 

Carousel ads are becoming a popular trend among social sites, as they offer advertisers a better way to tell stories through photos. Both Twitter and Pinterest have introduced their own versions in the past few months. Those extra photos may seem like a small addition, but they can expand the ad's ability to clearly portray a message.
