Most Wikipedians do not use video or audio very often or very well in articles, relying almost exclusively on text and photos. Perhaps the COVID pandemic has improved editors' skills in this area with all the Zoom calls we've had to make. The pandemic has also increased our need for multimedia as in-person conferences, such as Wikimania 2020, have been cancelled. This week Wikimania 2021 was turned into a virtual event (see this message from Janeen Uzzell on the Wikipedia-l mailing list).
The video and audio resources created to celebrate Wikipedia's 20th birthday demonstrate the flexibility of these media. The videos include a slick two-minute celebratory video, an hour-long video press conference from the WMF, and even longer deep dives produced by the community.
