Snapchat is expanding its "replay" feature for those disappearing messages, giving users an option to get another look at three "snaps" for a fee of 99 cents.
The feature is the first by the popular social network to get revenue from its user base in addition to advertising messages introduced last year.
Snapchat in May said it raised $537 million in a new round of equity funding.
The vanishing-message service did not disclose who bought stakes in the Los Angeles-based company, which came at a price estimated to give Snapchat a value of more than $15 billion, according to media reports.
