Twitter Buys Social Media Talent Agency Niche

Why social media stars love Niche -- and Twitter wants a piece of it.

"As more users and creators use different products as a way to share what's happening in their world, brands are also looking to partner with those individuals in hopes of generating moments that resonate with the people they are trying to reach," a Twitter blog post read.

Twitter did not disclose how much it paid to acquire Niche.

Rob Fishman, co-founder of Niche, told ABC News last year that his agency is the perfect way for even the biggest brands to connect with online influencers.

Some Vine stars are so popular they told ABC News last year they pull in six-figure salaries with their videos.
