Recommender systems function fulfills the principles of big data and therefore this area is approached as a big data context. The idea is to provide general view about recommender systems, how they function and for what purpose they are designed. This paper focuses on collaborative filtering, content-based filtering, demographic filtering, knowledge-based filtering and hybrid variations. In addition to that, possible commercial benefits are discussed in a service provider point-of-view.\nThis research is made as a literature review. References consists of scien-tific articles and a few area related books, most of these published in 2000-era. Commercial sources and blogs have been used in a few relatively commonly known issues. One of the priorities in selecting references was publishing date because recommender systems is fast-developing area of interest.\nAfter reading this research paper reader should have general understand-ing about most common recommendation filtering techniques. Commercial benefits and what to take in consideration when applying recommender system in use are also pointed out.
