I don't know of any other ones, the ROI is difficult to calculate.
The twenty years of webcasts were a blast, but extremely stressful. On WhatsApp you just click the camera icon. Back in the day I had to remain in contact with video server to adjust bandwidth settings constantly. Pre wifi I would have to run cables. And the software wasn't standard so I was always checking for the best solutions. We were so far ahead of the curve that virtually all the software companies gave us the software in exchange for debugging it.
Having my parents, and friends parents on the chat was my personal highlight.
An unforgettable, incredible 20 years! Thank you for being a part of those memories!
