As you can see in the slideshow below, Verizon spent more than $90 million on 15 spots, with the most expensive run being the multiple fist pumps clip with Jamie Foxx. AT&T, on the other hand, spend much less, but still it ran the "Work Things" video you can see below for $20.8 million estimated worth at mostly Fox, CBS and ESPN.
Next in line is Sprint with $51 million spent, mostly for Paul the Sprint guy commercial. T-Mobile counts on viral marketing and lets its plans speak for themselves mostly, as it spent the least from the major four carriers by a large margin, despite that its most run clip features a celebrity like Ariana Grande. Given the increase in postpaid smartphone subs of more than a million in Q3, T-Mobile obviously gets a good bang for its advertising buck.
