Software platforms were custom written to handle money collection and transfer, connecting caller and sex worker though neither could see anything but the platform's phone number, and metering the connection.

In concept they have a lot in common with platforms such as Ebay: the seller provides the picture(s), description, and sets the price, a percentage of which is kept by the platform.

In the sex industry, similar platforms emerged facilitating the selling of used panties and other odoriferous garments, and for "cam" video sessions, in which the customer, for a fee, can direct the woman on the video screen, and for a higher fee, have a private connection (no one can see caller or provider except each other).

The provider provided (say) 10 minutes of service, but got to keep all of the money (say 20 minutes).

When the Internet got relatively mature, sale of any sexual service not involving a minor could be made to anyone not a minor.

Leonard recorded her own voice informing callers of the contents of the next issue of High Society magazine before its publication.

Later she recorded others such as Annie Sprinkle "talking sexy".The sexually explicit conversation takes place between two or more persons via telephone, especially when at least one of the participants masturbates or engages in sexual fantasy.Phone sex conversation may take many forms, including: guided fantasy, sexual sounds, narrated and enacted suggestions; sexual anecdotes and confessions; candid expression of sexual fantasies, feelings, or love, and/or discussion of very personal and sensitive sexual topics.Nevertheless, phone sex should not be confused with prostitution wherein money is exchanged for real life sexual services or physical interaction.The editor of High Society magazine, Gloria Leonard, is credited with being one of the first people to use "976 numbers", then "900 numbers" for promotional purposes and soon as a revenue stream in the adult industry.Leonard convinced magazine owner Carl Ruderman to purchase more of these numbers and the business began to be successful using the magazine to promote the service.
