Blogger (Blogspot), acquired by Google in 2003, is a service created by Pyra Labs in 1999 to create and publish blogs.
A blog is a website that compiles texts or articles by one or more authors chronologically, and usually, in each article, readers can write their comments and the author can respond to them so a dialogue can be established. The design of each blog is specific for personal, journalistic, commercial, corporate, technological, educational fields.
Multimedia is any combination of text, graphic, sound, video, or animation files that can be played on a computer or other electronic device. Multimedia software is an auxiliary tool that automatically displays the information of the file to the user when the relevant file is played.
