I built one of the first location aggregation systems. Maybe the first, hard to be sure. My company had close relationships with all of the US cellular companies and built white label apps for them, mostly under the auspices of family safety (though many users were more concerned about the location of their partners than of their kids). Around the same time OAuth 1a came out and it seemed like a great ideal to offer a platform that leveraged these relationships to sell location to app developers, subject to consent and with a bunch of features to protect privacy. In the end, we had one app developer who was even remotely successful and the less privacy-focused aggregators partnered with the next generation of app developers and the product had no future. Nostalgia is fun.
