Need advice on entertainment product that solves no problem

Wanted to ask the IH community for advice on how to pursue a persistent idea that I have. It's mostly a thing that I wish existed but, with proper execution, I think many others would enjoy it too.

However, it is almost entirely entertainment value it doesn't solve any problem. So, I'm not really sure who my ideal user is, or how to determine that. It's a mass market type product. My thought is the value/appeal would grow with user count but getting the first users is going to be tough and I don't see many channels working out.

I can explain it, create landing pages, and optimize conversions but it's not something where I think blogging/content marketing/SEO would work to drive traffic. Honestly, there's not much to write about and even if I got creative it's not something people are searching for. They probably need to be told about it via word of mouth or just stumble on it, which I know is unlikely.

How can I drive traffic without a massive ad budget?

Edit, to elaborate on the idea. Imagine there was a monthly video series where a random person was chosen to spend a pile of money, say $1M, in a day. The video is the entertainment part I mentioned. It probably sounds stupid but with the right amount of creative storytelling etc I think it would actually make for an interesting 3-10 minute clip that many people would watch each month.

We could learn about the person, their finances, their family, how the money would be used (buy a car/house/yacht/college), etc, etc. and generally how it impacts their life. In my mind, the show/videos is a medley of Ashton Kutcher's Punk'd (the surprise factor), the PCH give aways (the money part), a documentary (story telling), and MTV Cribs (bling).

I know this probably raises other questions like, legal issues (is it a lottery?) and money issues (where does the $1m come from?) But I have solved those questions already and just need to figure out how to promote/would people have interest in subscribing to this like I would.
