Final answer:
A blog is a web-based publication featuring periodic articles, and it is often self-published using various platforms. Digital flipbooks and podcasts are other forms of digital content that differ from blogs by format and content type.
Step-by-step explanation:
A blog is a Web-based publication consisting primarily of periodic articles, which can be self-published on platforms such as WordPress and Adobe Experience Manager. Blogs may incorporate multimodal content including text, images, and videos. Another option for digital publication is the digital flipbook, which mimics a digital magazine and is viewed by scrolling left and right through pages on platforms like Issuu. On the other hand, a podcast is an audio show, which can be either original or recorded versions of existing radio programs, enjoyed by a large audience, reflecting on different topics and available on various streaming platforms.
