Aladdin has to be among Disney's greatest and beloved characters ever adapted. It all began in 1992, when Aladdin, the feature film, was released in theaters. Within its first week, it became a major blockbuster and grew to be so popular that a year later, in the summer of 1993, Disney decided to make a sequel to Aladdin featuring the return of the evil villain from the first film in The Return Of Jafar. Continuing on with Aladdin's popularity and the demand for more adventures, Disney created the Aladdin TV series a year later, in 1994. The show had 2 seasons and it become so popular and so high in demand that it exceeded the normal 65 episode limitation of a Disney cartoon series. With that, Disney made a 3rd season of Aladdin in 1995 which contained 8 additional episodes. After the last episode of Aladdin aired, Disney wrapped up the tales of Aladdin with the 1996 film Aladdin and the King Of Thieves.
NOTE: But even though it would be correct to classify the three movies as part of the series, they are not official episodes and therefore aren't included in the "first aired" and "last aired" categories.
