Advertising on Platonic Realms
Platonic Realms welcomes sponsorship by organizations offering goods or services of value to our specific target audience. We do not accept ads that are not directly relevant to the studying, teaching, or enjoyment of mathematics, and we do not accept ads placed by third-party agencies.
Both no-cost and low-cost banner space is offered on a month-by-month basis, with the location and cost of any given ad determined by bidding among member advertisers. If you are already a member advertiser or would like to learn about becoming one, please visit our advertiser's page.
