[3] In recent years, "vlogging" has spawned a large community on social media, becoming one of the most popular forms of digital entertainment.It is popularly believed that, alongside being entertaining, vlogs can deliver deep context through imagery[4] as opposed to written blogs.In addition, the convergence of mobile phones with digital cameras allows publishing of video content to the Web almost as it is recorded.[citation needed] Throughout the lifetime of the YouTube platform, vloggers have developed large social communities by expressing emotions of vulnerability and encouraging their viewers to do the same.The effect of this emotional exchange between strangers has been documented, for example, in the popularity of bereavement vlogs, in which grieving individuals reassure each other through friendly comments.[30] Oral proficiency exams were given to all students to reflect their current speech skills, after a year of teachings based on each of the groups preference.A 2014 study evaluated the contextual relationship between vloggers who shared that they had diabetes, cancer, or human immunodeficiency virus (HIV) and their audiences.[38] Hollywood is taking notice of this rising medium, and has placed its value ranked over other entertainment companies such as Marvel, which is also owned by Disney.
