I see "Big 4" on r/cscareerquestions a lot. It seems to have been invented by that sub as some kind of mythical club of golden programmer employers. It came from accounting/consulting where there are four really big consulting giants: (KPMG, Earnst & Young, Pricewaterhouse Coopers, and Deloitte). Interestingly enough, the above aren't known for being particularly nice employers. On the sub the inclusion in the "big four" varies a bit, Google is the only one who's always in it. Others sometimes included are Microsoft, Facebook, Twitter, Amazon, and Adobe.
