Anyone familiar with the ad campaigns from Motel 6? Does Tom Bodett ring a bell? As the story goes, the iconic phrase that runs through the Motel 6 ad campaigns started as an ad-lib from Tom back in the mid-80's. The phrase-- “We’ll leave the light on for you” -- was a fantastic, down-home way to let customers know that Motel 6 cared about them. Thoughtful. Reassuring. This phrase was designed to evoke comfort after a long day of travel.
