In early 2019, I posted three promo videos (called “logo reveal”) to promote the **S**cience, **T**echnology, **E**ngineering & **M**athematics community on our platform. It was in the pre-Hive era, so as you can imagine it used the logo and name that are now obsolete.

For those who missed that part of history, the name of the legacy platform was similar to STEM, but with an extra “E.” 
Like in [Embarrassment](https://hiveblocks.com/tx/546471d9d0eafc22a1291a8c92cf4f1ac00d610e), which we decided to get rid of.

The videos were pretty cool, though.

After noticing that they are still  used here and there by the [STEMSocial community](/trending/hive-196387), I decided to finally refresh them with the STEMSocial logo, and of course with “powered by Hive”.
Last but not least, all are encoded with the audio track that you liked so much. It was created by maestro @mobbs.

Below the videos, there are three animated GIFs, converted from the source MP4 material, along with a block of code suitable to be included in your posts.
Feel free to use those materials to promote Hive-powered Science, Technology, Engineering & Mathematics.
