Category killers
In the euphoric times , we were left wondering with how some products /services have almost killed some categories , there mite be many , but the biggest one must be mobile services , take a look at the categories that have been bruised , wounded or killed by it :: greeting cards /torches /fm radio /music player /cassettes & cd's /wrist watches /land line phone/camera /credit card ( mobile payment ) /alarm clock /laptops /video camera /maps /newspapers /Dictaphone /gaming consoles / calculator /bank( brick and mortar ) /TV , phew !! there mite be more , come to think of it what sounds a great idea currently always has a BIG threat of substitution and something like a mobile service is a good example of how one move can close or hit a current category , retailers need to look into the horizon and keep an eye on the trends and spot them early !
