Steam started their review with an overview of some numbers and acknowledging how the year has gone for everyone.
"As many of you already know, this past year had more than its share of challenges, with everyone's lives upended by the global pandemic. While Steam was already seeing significant growth in 2020 before COVID-19 lockdowns, video game playtime surged when people started staying home, dramatically increasing the number of customers buying and playing games, and hopefully bringing some joy to counter-balance some of the craziness that was 2020. This has led to new highs for monthly active users (120.4 million), daily active users (62.6 million), peak concurrent users (24.8 million), first-time purchasers (2.6 million per month), hours of playtime (31.3 billion hours), and the number of games purchased (21.4% increase over 2019)." - Valve
At 2.6 million new first-time purchasers each month, and a total of 120.4 million active monthly users, Valve was able to set quite a few record-breaking new highs.
The 2020 data for Steam shows that PC gaming is still on the rise, and even with the release of next-gen consoles, PC gaming is still able to outshine them.
Valve goes on to mention a bunch of other cool statistics, such as the usage of Steam Points, VR Usage, Controller Usage, and even the total amount of Data delivered through Steam (hint, it is A LOT)!
