Pandora streams music over the internet which is related to a artist or song that you have entered at the beginning. The service is great to find new artists that make a similar kind of music than artists that you like to listen to. The service was completely free until now.
They have decided to add advertisement to their service. According to Pandora’s CTO Tom Conrad about 10% of the users are receiving a nine second advertisement once a day. This looks like testing the waters for me. If few users complain about the ads they might introduce this to all listeners and probably even increase the amount of ads that are displayed each day.
I personally think that it is not such a big problem if you compare it to terrestrial radio stations for instance. It could become one if they would decided to increase the advertisements. One should also consider that websites that offer such services have to generate money somehow to be able to pay the bills for servers, bandwidth and service.
A alternative would be finetune.com which can also be used to get new suggestions.
What is your opinion on the matter ?

I think it’s ok.
I use Pandora at work. And I get the commercial (so far I get a McDonalds ad) once a day when I change between the stations I have programmed.
It doesn’t bother me yet. But in Launch (Yahoo service) I don’t use it, because their ads are 30-45 sec long and they are repetitive every 8 songs or so. That way it does gets annoying.
Yahoo Launch: Better than normal radio
Pandora: Better than Launch.
Yeah I heard my first add a few days ago. I posted about it and still haven’t decided what I think. I don’t want the service to go away but Im not sure how I like the idea of my relaxing station playing some blaring ad for whomever.
Just like good ole Boz Scaggs said —can somebody loan me a dime, it’s time to pay the fiddler!!
