A Brief History Of Multiplying Paychecks

Emmis' KZLA, to my knowledge, was the first to do it under the name "Double Your Weekly Salary" and thus they are the ones trying to protect their first use of the concept.

KUPL, Portland, and KMPS, Seattle did it next (in the early 2000's) and continue to do it at least several times a year as "Double Your Paycheck." Then, a couple years later, San Diego's KSON (more than) jumped in followed by WKIS, Miami and Atlanta's Eagle.

Now, in Vancouver, JR-FM kicks it up a notch with the start of the fall book!
