I don't use Steam much, but they are a computer-based program and store, and I think computer games are not the only thing they should sell in today's market. Offering more they just games does start to bring the company's center away from gaming, but I still think games will be the number one selling genre. I think we can compare what Steam can become to Apple's App Store (and even Google Play) where games are the number one selling genre, but not the only profitable thing in their market. Selling various categories and selections of different programs can bring more buyers into their store, and a customer might look at Steam's selection for one thing, and find another product they are interested in. Considering how many different places we can purchase and different kinds of software, I think Steam is doing this for the best of their profits, and to increase their customers, and it might not be a bad thing. If I can buy Photoshop, MS Office, or an antivirus software off their site all at the same time, I think that makes my life a whole lot easier.
