Business Idea no. 9

Using the huge potential in large cities with high buildings and skyscrapers, to build a local Advertising Network, and connect local businesses, shops and companies to home owners. This business idea can be an online marketplace of publishers & advertisers, collecting commission fee as its main revenue stream (business model).
It is even more demanding in lockdowns caused by the 2020 and 2021 Corona Virus pandemic, because the number of ads viewers/impressions is higher by default.
