Maybe A Fun Idea

As I have started working on a startup and explored all the possibilities of marketing (especially online) I have realized how incredibly valuable and vast the digital marketing industry is and how much money is poured into this sector. (Estimated value of around $40 billion! - https://www.grandviewresearch.com/industry-analysis/digital-marketing-software-dms-market) It definitely does make a lot of sense as to why this industry has become so valuable - more people are striving to be independent and start an online business or side hustle. Unless you hit the jackpot, gaining any traction online with your business requires (in many cases) a combination of nifty marketing strategies and paid acquisition channels.

Many people and businesses have taken advantage of this trend - a trend where almost anyone is willing to pay to get their landing page recognized - and have made money doing so. Some have been incredibly creative in their approach of making money through advertising. In 2005 an English student created a home page on which he sold each single pixel for one dollar. All the pixels on his website sold out - take a look at the full story here: https://en.wikipedia.org/wiki/The_Million_Dollar_Homepage.

This story got me thinking - there must be equally "banal" methods of selling advertising space in a fun and simple way which attracts users in large numbers and allows for incredibly cheap and also permanent advertising.

What do you guys think? Is such an idea a "one-hit wonder" or have other such ideas that you know of been successful?
