Example embodiments provide apparatuses and methods directed to a system for presenting customized advertisements and branding in conjunction with an audio-visual presentation, e.g., an online slideshow with audio enhancement, played on a player module on an access device. In example embodiments, the online slideshow includes a customized pre-roll advertisement, a customized post-roll advertisement, and/or a customized banner advertisement on the final slide of the slideshow. The system also might customize the GUI views displayed by the player module which plays the online slideshow and/or the player landing page on the CDN that hosts the player module. In example embodiments, the system might base the customization on branding (e.g., in support of “white labeling”), seasonal themes, and/or personalization.
