Browser testing has come a long way in the last 15 years. Back then I worked for a small embedded browser company with a test team that manually checked websites. This was tedious, and inefficient as there are only so many sites a person can visit in a day.
When I joined Ekioh, I was pleased to see they had taken a more modern approach from the start. There was a genuine passion for product stability and a strong desire to avoid the embarrassment of regression bugs.
