To buy media, you can follow these steps:

1. Contacting Publishers: This is the traditional way of buying media. You can directly get in touch with the publishers who own the media space you are interested in. This could be newspapers, magazines, TV stations, radio stations, or websites. You would negotiate a price and placement for your ad.

2. Through Self-Serve Portals: Many publishers and ad networks now offer self-serve portals where you can directly purchase and manage your media buys. These platforms allow you to select your target audience, choose your media format, set your budget, and launch your campaign. Some popular self-serve ad platforms include Google Ads, Facebook Ads Manager, and Twitter Ads.

3. Contacting Ad Networks: Ad networks act as intermediaries between advertisers and publishers. They aggregate ad space from various publishers and sell it to advertisers. By working with an ad network, you can access a wide range of media spaces without having to negotiate with each publisher individually. Some well-known ad networks include Google Display Network, Outbrain, and Taboola.

Remember, the best method for you will depend on your specific needs and resources. It's important to do your research and consider all options before making a decision.
