Considering that genies are a "magical spirit believed to take human form and serve the person who calls it", I would say that a title which has a character who fits this description would qualify. Some people have said that Aa! Megami-sama! OVA and Shinpi no Sekai El Hazard are genie titles.
This is a sub-genre of the romantic-comedy genre. To qualify, you have to have a single, dateless, nice guy who suddenly finds himself surrounded by a bunch of hot girls/women who are interested or attracted to him to varying degrees. The male lead may also live with many of these girls.
Older anime titles, from the 80's back. What the actual amount of time that has to expire must be is unknown to me, but as a rule of thumb, a title should at least be 10-years old. Lupin III is an example of a classic title.
