The “I’m Lovin’ It” slogan is actually a part of McDonald’s zeroing in on the “urban” youth market. Begs a couple of questions, doesn’t it.

There are other instances where words are used in advertising in nonstandard ways, in order to reflect how many people pronounce them, Case in point: Budweiser once marketed “Artic Ice” beer, dropping the the first “c” in “arctic” according to common though non-standard usage.

One of my profs once said of language that what it does is change. Language always and constantly mutates and changes. Language change happens according to common, popular usage and happens more slowly when there is a codified set of rules that determine correct usage, spelling, pronunciation, etc. What we are seeing here, we can argue, is advertising as helping accelerate possibly lasting changes in standard written English.
