I had never even heard of Pandora. A quick check seems to suggest that they are America-only, Alexa rank 800, while Spotify is international, rank about 80. As a European I hope I am excused. Yes, Pandora seems to be older. How intense the competition was when it started I have no clue. I'd say it was bleeding edge in either case, in those days broadband internet was not so widespread, not to mention mobile data.
