Bitstrips' free mobile apps triggered the craze by making it easy for anyone with a smartphone or tablet computer to quickly create and post comics featuring themselves and a friend depicted in different scenarios. The apps provide thousands of comic scenes to choose from, then allows each user to create their own captions.
The overwhelming response surprised Blackstock and Panth, who had to scramble to increase Bitstrips' computing capacity to keep with the intense demand. They now have a staff of 17 workers and have raised $3 million from Horizons Ventures in Hong Kong.
