Mr. Coffee, and the Rest....
There is a little-known factor that explains why new coffee brands and new coffee-making equipment often garner raves.
It is this: Once your tastebuds become familiar with a given brew - no matter what bean or brand or equipment was involved in its making - they become overly familiar with it, "bored," if you will.
Which means that any new brew will wake them back up again, at least for a short time, until the tastebuds become familiar with the new one. By that time, many an impressionable coffee customer has plunked down money for the latest coffeemaker or stratospherically-priced coffee beans that have been through a civet cat's bum.
Mr. Coffee was not an exceptional coffee maker by any means - it was just that the change in method produced a new brew with which peoples' taste buds were not familiar. That and having Joltin' Joe DiMaggio in the commercials moved a lot of merchandise.
Full disclosure: Perc user here - one who has been through every fancy drip coffeemaker, grinder, grind 'n brew machine, and fancy coffee bean known to Man.
