In a world that is weary of ad gimmicks, Instagram has provided brands with a creative new medium through which they can reach as many as 50 million users (turned amateur photographers) in an artistic and engaging way.

After Facebook's $1 billion acquisition of the startup in April, at this point if you haven't heard of Instagram you probably still use dial-up, have a flip-phone the size of a chinchilla, and aren't reading this site; but for the uninitiated: Instagram is a photo sharing site that allows users to share snapshots of their lives through artistic sepia filters.

Many brands have taken advantage of the opportunity to give consumers an intimate look at what their products have to offer. 
Brands have flown highly influential Instagram users (with 100k-plus followers) to Abu Dhabi to shoot sailing races, given consumers behind-the-scenes looks at fashion shows or sporting events, organized "Insta-walks" ... Playboy has even shown a surprising, nostalgic side of the magazine by sharing vintage pics of their models wearing clothes.
Business Insider Advertising has compiled a list of the brands who are doing this in really cool and surprising ways that make people want to share.
