Sony Interactive Entertainment (SIE) is a multinational video game and digital entertainment company wholly owned subsidiary of Sony. The SIE Group is made up of two legal corporate entities: Sony Interactive Entertainment LLC (SIE LLC) based in San Mateo, California, United States, and Sony Interactive Entertainment Inc. (SIE Inc.), based in Minato, Tokyo, Japan. Their Japanese branch are the creators of the PlayStation brand of video game consoles.
They created the PlayStation brand, some of the best consoles and handhelds ever made.
They pay attention to what their fans want, and they deliver; they even started bringing back old IP's like Wipeout and helped Activision with reviving Crash Bandicoot. They also announced at PSX 2017 that they're going to bring back MediEvil, another classic IP with a small, but loyal, fanbase.
They also have respect for their gamers and faith in them; they are against the "Games as a Service" model and have shown a commitment to single-player games. Despite the opportunities being present, they didn't incorporate any microtransactions or loot boxes in Horizon Zero Dawn and God Of War (2018). The company is far less likely to give in to microtransactions as other companies like Electronic Arts.
They, along with Nintendo, are one of the few publishers that prove EA's narrative of "single-player games don't sell well" to be completely false thanks to their commitments to producing high-quality single-player games.
Because they own many IP's like the ones above, there is always at least a handful of reasons to buy their consoles. Not only that, but their IP's also cover many genres, so there's something for everybody.
They don't rely on two or three franchises as much as their competitors do, and they don't milk them dry.
Sony has shown that they don't abandon their new IPs when the games flop critically or commercially; games like Knack or Gravity Rush wouldn't have received sequels if they did.
They support their developers by allowing them to do whatever games they want, which is a really huge risk, but as a result, many developers love working and making games for them.
Instead of making Guerrilla Games do a sequel to Killzone: Shadow Fall or another first-person shooter, Sony allowed them to make an entirely new game altogether in an unfamiliar genre. That game was, of course, the science-fiction action RPG, Horizon Zero Dawn.
Even after a string of disappointing games, they gave Santa Monica Studio the support they needed to bring God of War (2018) to life instead of simply giving up on them and shutting the studio down, unlike other certain publishers. The results really paid off.
Before Insomniac Games started developing the upcoming Marvel's Spider-Man game, Sony asked them to develop a Marvel game (with Marvel's OK of course), however, they told them that they should choose what Marvel character their game should be based on (and they chose Spider-Man). It really shows how much freedom they give even to their once second-party developer.
Naughty Dog once admitted that if it weren't for Sony, they would have never been able to do big games like the Uncharted series.
Even when Sucker Punch Productions spend a considerable amount of time developing their games, Sony still allows them to do so without the need to rush them to release before a deadline. As a result, many of their games are always well received.
Their consoles would do more than gaming; for example, the PS1 could play CD songs, the PS2 could play DVD and songs too, their PS3 and PS4 play DVD, Blu-ray and digital movies, which can bring in more customers.
Their first-party games are usually very cheap on the PS Store.
Made lots of great motion accessories and games, like the Eye-Toy for the PS2, PlayStation Move controller and the PlayStation Eye for the PS3, the PSP Camera for the PSP, the PS4's PlayStation Camera and VR, and the PSVita itself.
In response to the COVID-19 pandemic, they launched the Play at Home initiative, giving away free games to PlayStation gamers with no strings attached.
Due to some PS3 consoles and PS4 consoles not having backward compatibility, they introduced remastering games, where they re-release old games with new features and technical improvements.
All of their consoles and handhelds are very powerful for their time with the exception of the PS2 (though it was still very powerful).
They usually support their consoles and handhelds long into the next generation before discontinuing them, with the PlayStation 2 being up and strong for 13 years before it was discontinued.
Another example is the PS3, which although has stopped production, still gets new games and hotfix updates after 15 years!
Their handhelds can play some old consoles games like the PlayStation very well. Their handheld games also have graphically fidelities that are close to home consoles.
Introduced Cross-Buy, where if you buy a game for PS3, you'll get a free copy of the Vita (PlayStation versions only).
Their handhelds were the strongest competition to Nintendo handhelds (though they still didn't succeed).
Usually, years after their consoles and handhelds were made they usually re-release the console/handheld again in a different model that's cheaper and with improved stuff.
The games they make usually have characters that'd become an unofficial mascot for their consoles, like Crash Bandicoot for the PlayStation.
Many games that were exclusive to PC or other consoles would get ported to PlayStation consoles.
Most of the time when they make mistakes (like the original PS3 model or Knack's rushed development) they learn from it.
When people reacted negatively to Microsoft's Xbox One at E3 2013 they took advantage of that by announcing that the PS4 won't have any of the restrictions that Microsoft was going to impose for the Xbox One. Thus the PS4 ended up outselling the Xbox One (even though they always did outsell the Xbox consoles).
Aside from the PS3, PSP & PS Vita, their consoles are usually the best selling for their generation; in fact, the PS1, PS2 and PS4 are one of the best selling consoles ever made.
Their PS Plus service, a subscription where you get lots of awesome monthly games (sometimes even full AAA titles), more discounts on stuff (up to 75%), and exclusive beta access for certain games.
The free monthly games program even includes their own 1st party titles; a recent example is when they had both Bloodborne and Ratchet & Clank (2016) on there in March 2018.
After a lot of prodding and bad PR, they have finally decided to allow cross-play. They started by reversing their stranglehold on Epic Games accounts for Fortnite, as have an open beta for Fortnite with cross-platform gameplay, commerce, and progression.
They usually have strong marketing campaigns for their products. The most over-the-top they have gone is having a New York underground train custom-fitted and painted with a Spider-Man theme.
While they are the creators of the PlayStation and make exclusive games for it, this doesn't mean that they are strangers to PC gaming, as they've been recently porting some of their games to PC, and most of them have great ports, specially God of War (2018) and also made a firmware update tool for the DualSense controller for Windows. They also have a PC porting division called "PlayStation PC".
They created a studio called PlayStation Productions, which focuses on adapting Sony's games into video games and TV shows, that way Sony can make the games themselves and make the games closer to the source material.
