DLC has been a thing for a while, even before the internet existed, so you couldn’t really download things. They were known as expansion packs, a term now used mainly for RTS games and MMORGs these days. And most of these were really good. The Frozen Throne, for example, was excellent. Yet since the beginning of things like Steam and the company stores (Xbox live store and the PSN store) the market has become saturated with crappy day-one DLC that allows consumers to buy power.
