GoPro, a brand synonymous with extreme-sports videos, just filed for its IPO.

GoPro first announced its intention to file way back in February. As we said three months ago, the filing was inevitable: Last year GoPro founder Nick Woodman publicly said the firm was “getting itself prepared for an IPO.” Later, the company brought on a CFO, former Qualcomm Atheros exec Jack Lazar. All the while, GoPro consistently pushed for mainstream exposure and even invested in a Super Bowl ad.

GoPro essentially owns the activity camera market, and has reportedly doubled its sales every year since launching in 2004. GoPro’s wearable cameras often lead to entertaining, first-person videos like one embedded below.
