> I’m wondering how long it will take for large companies to realize that people are gradually adapting and starting to look for information on sites other than Google search bar.

Hopefully it will take them a very long time. I don't want companies to start poisoning online communities with their hidden advertising. When I visit an online community, I want to read about the real thoughts of real people that are hopefully much smarter than I am, and maybe even post a few of my own. No community wants paid members with ulterior motives and conflicts of interest.
