If you listen to a station often enough, the ads get ingrained in your mind subconsciously. I still remember the number for the Bailout Group is 800-775-0019, Kelly Lynn Daniels of Prolixus likes it Thick AND Wide, Major World has over 3000 quality new and pre owned cars in Long Island City, Ultrabar in Teaneck has a world famous patio, every word to the Rye Playland jingle, Queens College boasts about its Inspiration Opportunity and Discovery, Galaxy Visions and their promise to take your old website and update it (Niko did the voice for that spot), Tony Roma's, Palace Hair Salon in Franklin Square, Elite Palace, Guaranteed Consumer Funding will ship a brand new computer right to me for $29.95 a month with no credit check so I won't be turned down, Masterbeat.com is the one-stop shop for music downloads, and a whole lot more ads including almost every club that advertised often. The ads I remember most are the ones that advertised most often, and I didn't make any effort to specifically remember every ad.
I didn't listen to any Pulse 87.7 airchecks recently, or look at the client list, this is all unaided response to whatever comes to my mind when I think of Pulse 87 advertisers. Pulse went bankrupt 5 months ago, and I still remember specific details of their ads. The more the advertisers spent, the more impressions get ingrained in the listener's minds. I've tried to patronize as many advertisers as I can, for example Elite Palace will be my top choice for my wedding venue if it's still around 5 or so years from now, I buy my dance music from Masterbeat, I've eaten at Tony Roma's, I will shop for a car at Major World. Part of what made Pulse 87 so special for me was the local ads from small businesses that don't advertise elsewhere. Those ads did pay the bills for Pulse, but didn't pay the debt Mega Media had from before it signed on.
After Pulse died, I stopped listening to the radio as much as I used to, the Internet stations I listened to were commercial free. Just today for example, I was forced to listen to 92.3 Now for 3 hours straight, I do not remember a single commercial. But I'm sure if I listen to Now for 3 hours every single day, or even 1 hour a day, I will remember the ads.
