I too, noticed this misuse in Michell Obama's speeches. Unfortunately, it is becoming a trend that we need to speak out against. As much as I would like to test a particular product, I have no confidence in a retailer that advertises their product using a narrator that has less than an acceptable command of the English language. I have written this company, informing them of my disdain for what I consider, an intentional use of the non-word, SHTRONGER. The word is STRONGER, pronounced with an "st" sound as opposed to the "sht" sound. Whenever their commercial airs I cringe, and immediately mute the TV.
