TechCrunch: Snapchat is introducing another revenue stream in the form of on-demand geo-filters. Anyone with a bit of design savvy can pay Snapchat to create and distribute their own custom geofilters in a specific area for an allotted time. The minimum size for these geofilters is 5,000 square feet and the minimum amount of time one can exist is 30 minutes. The turnaround time for review is about a day, and pricing starts at $5.
