It's about product placement , if you think of certain things then certain names automaticaly spring to mind (computers / microsoft).
I worked for a company that makes paint and was very well known and respected (Sikkens) they were bought by Akzo Nobel.
They realised that changing the logo on the tins to Akzo would lose them customers (people going "who the fuck are Akzo?) so they just added the name and gradualy the Sikkens name was made smaller and the Akzo name made larger so people would accept that Akzo was Sikkens, after a few years they removed the Sikkens name altogether.
Power of Brand names.
