This week, water, but the same happens over and over again in every sector: https://theconversation.com/how-thames-water-came-to-be-floo...
As of right now, the single greatest example in modern business history is Uber. Although they continue to trim their operating losses and it appears they may reach sustainability ($14.1b revenue with $8.5b operating loss in 2019; trimmed to a $1.8b operating loss on $31b in revenue the past four quarters). Their history of loss generation is astounding. Upwards of $30 billion in operating losses since 2009. Even in an ideal scenario it'll probably take them 10+ years after they finally reach an operating profit to turn that net positive.
I feel like the startup game for a while now has been… and the numbers are arbitrary but I don’t think the dynamic is wrong… raise about $100 million to get a total of $10m in revenue and then be worth $1b. That’s not business as we think of it.
I guess some companies like Yahoo were never profitable but some people got rich buying and selling shares.
