Blogging allows people to share their creativity and opinions with the world. Blogs originated from bulletin board systems and online forums from the 1990s. There are different types of blogs including personal blogs, corporate blogs, and microblogs. Blogging employs various technologies and formats like text, photos, videos, audio and has influenced how businesses, news, and other systems operate. It has grown more prominent since the 2000s as a new media and is now used mainstream by individuals, politicians, and businesses to shape public opinion.
