Netbeans 8 has a long one and IntelliJ IDEA 14 has several short ones. But in contrast to its competitors Eclipse Mars has no promotion video. Up to now. My 13-year old nephew and I proudly present the unofficial Eclipse Mars.1 promotion video:
IMHO proprietary and open-source software should compete in the area of technology and usability independent of their license and pricing. I see promoting as part of usability, e. g. to tell the user what is new and what has changed before she or he decides to use or not to use it. In my opinion, Eclipse can still learn a lot from its competitors in this respect.
Update 2015-10-05: Video updated (Gradle support added); Mars SR1 replaced with Mars.1
