DID YOU KNOW?
Did you know that Steam controls the largest share in the market for PC gaming? It was the digital distribution platform created by Valve Corporation. According to Bloomberg, Steam owned 75% of the market in 2013. PCGamesN then reported that Steam reaped a record $4.3billion in sales in 2017. That is almost 18% of the $32.3billion sales made by the industry that year. That record-smashing number is not an outlier. Steam was making numbers like this since 2014 when it recorded $1.5 billion in sales. This is according to reports by SuperData, a market research team. This included more than $400million from their three best co-op games then. At the time, it was Dota 2, Counter-Strike: Global Offensive (CS: GO), and Team Fortress 2. To this day, co-op games are still popular with online gamers.
Steam also helps independent developers and designers through the use of Programming Interfaces. This helps people use Steam to get profits from their games and designs. Because of its success, Valve decided to expand Steam and launched a stream of other products. These were Steam Workshop, Steam Greenlight, and Steam Music. Steam Hardware and SteamOS were being sold starting 2015. Next, came Steam Machines, which are pre-built gaming computers. These devices have near flawless connectivity with the Steam game distribution platform. In 2016, Steam brought out SteamVR, followed by Steam Direct in 2017.
