Template:RefimproveTemplate:About DeadAIM (originally De-Ad AIM) was a program created by James Dennis<ref>Template:Cite book</ref> to add new features such as tabbed conversations (which ended up being available in standard AIM until its shutdown) and to disable the advertising in AOL Instant Messenger (AIM).<ref>Template:Cite magazine</ref><ref name="tech_Show">Template:Cite podcast</ref> The last release of DeadAIM was version 4.5 in 2003.
In mid-2003, the rights to DeadAIM were sold to America Online effectively ending the development of the program.
JDennis was able to modify the framework of AIM with the use of API hooking. DeadAIM used an OCM file, similar to a DLL, to load into AIM. JDennis had benefited greatly by creating somewhat of a partnership with AOL. This allowed him to add several features more easily and also allowed him to create DeadAIMRegIn, an official AOL bot, to confirm registration information and prevent software piracy.
