The Only Way is With Publicity
If your brand is to succeed and become popular, you need to attract publicity. Advertising no longer works. Years ago, your popularity depended on your advertising budget. The only thing advertising can do now, is maintain a popular brand.
So what can you do? Create a product, brand and story that is worth talking about. Your aim is for people to tell the people they know about you, and for the media to want to be the first to write an article about you. For this to happen, you can't deliver just what's expected from you. You need to go a step further and be remarkable. Have something that makes you stand out.
Don't forget that a good story is essential here. Give a lot of attention to it and a good twist. No one wants to hear about the graduates that secured funding and started a company that develops software. They want to hear about the college drop-outs that bootstrapped and launched their first product with no backing and with everyone telling them that they'll fail.
Create something worth talking about and people will follow.
