And Navteq, Tele Atlas, TomTom, and a few more... They don't have the marketing skills of Apple and Google, but they don't need it because they are not consumer-focused companies.
Yes, you are right. I knew that, but I listed them because they were kept as independent subsidiaries, but thanks for making it clear.
I remember when that happened, and was pretty sure that a bidding war would start involving Garmin and Google, first for Navteq, and then for Tele Atlas, when they both were acquired (Google Maps used data from them, and it seems like they still do for some countries according to their Terms of Service: [1] and [2] as as examples).
