Twitter is expanding its #stickers feature, giving brands the opportunity to create their own promoted stickers in order to engage with consumers.

They were originally introduced as a "fun new way for Twitter users to add a pop of creativity to photos and connect them to the world", and the social platform now hopes brands and companies will pay for access to promoted versions.

Pepsi is the first company to take advantage, launching a library of 50 custom #stickers for users to add to photos they tweet as part of its ongoing PepsiMoji marketing strategy. 

This is the biggest collaboration yet between the two brands, meaning Pepsi has been allowed to create far more #stickers than the packages of either four or eight that will usually be on offer.

Twitter says that millions of photos have been tweeted using #stickers since the feature was introduced.
