Hi NormK, CyberJack and Bonnar_Bloke,
I sometimes get dismayed why some brands appear to stop advertising. Brand awareness has to be maintained and if rivals keep appearing periodically in television and radio advertisements and they do not, they shouldn't be surprised that sales decline.
I notice the Korean car makers as well as that electronics giant, keep putting out attention getting ads with striking and innovative imagery and music, just as the Japanese did in the 80s, while the others are far more in the background in media, despite the actual products themselves being nothing extraordinary to current standards.
Why do the longer established brands continue to rest on their laurels, apart from Mitsubishi with their successful and catchy "living out the back of the car" jingle. They may have the better product but we all know the power of hype and the danger of people falling for it and shifting to the rival's product even if it isn't as good.
