If you were one of the 1,502,898 adults who tuned-in to a Las Vegas radio station last week, you probably heard a commercial for the Panda Law Firm (aka Peters & Associates).

"Advertising on Las Vegas radio stations has been an integral part of the firm's growth," says Scott Chatley who has been handling the marketing for Panda law since 2010. "We bought our first radio commercial in 2011 and have been on the air ever since."

Market research affirms Mr. Chatley's use of radio advertising to expand the firm's caseload.

Each week, Las Vegas radio stations reach significantly more local consumers who are likely to hire an attorney than are reached by local TV, local newspapers, or streaming audio sites such as Pandora and Spotify.
