Abstract: There is provided a system and method for converting advertisements in a first Internet Application (IA) format for providing a presentation document using a second IA format. There is provided a system comprising a processor configured to obtain and retrieve an advertising script in the first IA format including referenced media assets and an interactive function, translate the interactive function to generate a translated function in the second IA format, generate a wrapper function in the first IA format implementing the interactive function, and provide a container document in the first IA format embedding the wrapper function and the presentation document having the translated function and the referenced media assets, wherein the translated function triggers the wrapper function. In this manner, presentation duties can be handled by a single IA format, avoiding rendering and performance issues resulting from the conventional method of using two IA formats concurrently for presentation.
