Obviously most companies mix successes and failures, but in recent years Sony has been pushing out an unreasonable number of failures with no successes to show for it.
I don't see any innovations coming out of Sony. I don't see them leading the way in any particular sector when it comes to consumer electronics. In audio products they're nobodies, in computing they make so-so non-descript equipment, in photography they've lost almost all the ground they once had to Canon and Nikon, in video they are being trounced by the likes of Samsung, LG, and Panasonic, and in cell phones they've just about been wiped off the face of the planet by Apple and Android handset manufacturers.
About the only sector they seem to be doing okay in is consoles, which from what I understand are not massively profitable, and are on the way out.
