How long should my content be to keep viewer attention?

Every rule about content length has been broken - Gymkhana proved that content over two minutes can get hundreds of millions of views despite people saying it wouldn't work. The answer is to do both short and long form content. Look at the platform: YouTube is perfect for longer form content, Instagram has reels for under 60 seconds and IGTV for longer pieces. Weekly or biweekly vlogs on YouTube have shown success. Think of it like food - you don't want the same restaurant every night. Consumers consume long form, short form, and quick scrolling content, so provide variety across different platforms.
