Users constantly adopt new behaviors, preferences and technologies. Social networks play catch up, adding new features and making changes to the user experience. This creates new opportunities and challenges for PR pros. Because the updates roll out so quickly (and sometimes without much fanfare), it’s easy to miss the latest changes.
Here’s a roundup of this week’s social media news and updates that may impact how you conduct social media marketing:
Pinterest has some new features up its sleeve. The pin-tastic social network is working to roll out new feature to its budding advertising platform, allowing brands to target their current customers who are on the social network.

Instagram 
Instagram ads travel across the pond. For the first time, brands can use Instagram to advertise in the UK. Brands such as Sony Music, Starbucks and Estee Lauder will be among the first to participate.
Want some Twitter with your movie? Since Twitter conversations naturally flow around entertainment, it’s only natural that they’d roll out a Twitter Ads feature geared towards movie buffs.
