Sok kutatás vizsgálta a különféle médiának a tudásszakadékokban játszott szerepét. Némelyik szerint a szakadékokat a nyomtatott média közép- és felsô osztály orientáltsága teszi valószínûvé. Mások szerint a tévé tudáski-egyenlítô szerepet játszhat. Kutatások szerint a közönség indokai a média használatára eltérôek lehetnek, s ezek eltérôen hatnak a tudásra. A média iránti figyelem, a feldolgozás és a függôség viszonyai jelentôsen hozzájárul-hatnak a tudásszakadék megértéséhez. Az e téren folytatott kutatások gyü-mölcsözôen kapcsolhatók össze a média felhasználására, az általa nyújtott kielégülésre és a tôle való függôségre vonatkozó kutatásokkal.
