Stickers are "bigger, richer, more emotive" than emoticons, according to BlackBerry’s head of Product Marketing, Jeff Gadway. They take up their own line in BBM chats, and eventually they might be animated. While a small number of stickers will be free, most will cost $1.99 for 20 to 25, although that price might be changed depending on how well they sell at that price. The stickers will be sold in the BBM Store and will be available next week after an update to the BBM app.
Stickers have been popular on other messaging apps and are the starting point for BlackBerry's goal to sell virtual-goods on BBM. Eventually, companies will be paying BlackBerry for the right to set up discussion groups in BlackBerry Channels, something that is being tested right now. Sponsored invites are also part of the current beta test. At the end of the day, we wouldn't be surprised to see the company spin-off BBM to take advantage of the insane valuations given to messaging apps right now.
