Steam's Android app has added a selection of new non-gaming categories, according to Engadget.
There are ten additional categories, all of which are currently empty.
The new categories include Accounting, Animation & Modelling and Design & Illustration.
Having just released the beta of Source Filmmaker it seems likely that Valve could move into distributing illustration and animation software. Valve already offers books and movies through its online store, so what's to stop Steam becoming a real App Store contender and releasing content for pretty much everything?
With Valve already allowing its community to vote which games it should distribute through Steam Greenlight, consumer may get a say in what other kinds of apps they would like to purchase through the site.
Steam's summer sale began last week and runs until July 22nd. Many fans are hoping that Valve's generous discounts will eventually extend to software…95 per cent off Photoshop perhaps? That would be lovely.
