Professional Rapid Online Chess League

The Professional Rapid Online Chess League (PRO Chess League and abbreviated PCL) is an online rapid chess league operated by chess.com. It was preceded by the United States Chess League, which announced in 2016 that it would be renamed, reformatted, and opened to cities from around the world, and moved to the website chess.com.
In its inaugural season, the PCL comprised 48 teams, whose members included some of the highest-rated chess players in the world, including the reigning world champion Magnus Carlsen, and other elite players including Maxime Vachier-Lagrave, Hikaru Nakamura, and Wesley So plus over 100 other grandmasters. The 48 teams represent cities in five continents.

Qualification.
In order to combat the large league, Shahade decided to cut the league from 48 teams to 32 teams as he believed the inaugural season was "a bit too large and chaotic".In order to determine which teams would return, he used the following:

The qualification tournament took place on November 3 with two qualifiers. The event format was stated on the PRO Chess League website.
Super Saturday and Super Sunday.
For 2018, the PCL introduced a new match format which allowed teams to play outside of their division. In these matches, each team played one single four-game match against eight other teams on Saturday, and another eight on Sunday. Once every team had played sixteen other teams, the total match points were added up. The following prizes were given:

Critic response.
Supporters say the league's worldwide distribution, the prize money, and the participation of many of the world's top-rated players may create a new level of competition and awareness for the game. It is anticipated that the new formats are leading to a "rise in popularity of online and rapid chess". In addition, the PCL has the potential to dramatically change chess culture and could lead to corporate sponsorships. This change from an "individual and slow game," to a relatively quick and team format, has made the offering more viewer friendly.
In a 2017 article, Greg Shahade made a similar statement to what Eric Rosen mentioned. Shahade talked about the league featuring worldwide team competition, using the scheveningen system which gives lower rated players the chance to pull upset each week, and having the chance to "revolutionize chess".
In an article written by ESPN, Viswanathan Anand spoke about how convenient it was to play online compared to playing over-the-board.
