What the second last biggest content?

The term "second last biggest content" is a bit ambiguous, but if you're referring to the second largest type of content in a specific context, it would depend on the medium or platform. For example, in social media, video content is often the largest, while images might be the second largest. In terms of websites, articles or blog posts could be the second largest form of content after videos. Please clarify if you meant something different!
