NEWSFILE CORP - Gen Z social media app Frog recently launched the SUPmarket pop-up activation across UK's university campuses, following the success of its first SUPmarket pop-up held in London's Piccadilly Circus last month. The SUPmarket activation takes its name from the app's 'SUP' feature, which centers around creating real-life, unfiltered video stories that can be shared privately or publicly with friends on the Frog app.
