First official Overwatch League match

On 10 January 2018, the first official Overwatch League (OWL) match took place between between San Francisco Shock (SFShock) and Los Angeles Valiant (LAValiant), both from California, USA. LAValiant took the match 4–0. The encounter followed a pre-season of qualifying matches to establish the 12 inaugural teams that began on 6 December 2017. Concurrent viewers on the League's official Twitch channel topped 415,000 on the first day of play. The OWL is a professional eSports league for Overwatch, developed by Blizzard Entertainment, which also oversees the League. It follows a similar structure to North American professional sports, using a set of permanent teams and regular-season play to determine each year's winner. The final of the first season was set to take place on 11 February 2018.
