A History Of The Whttp://pcgames-download.net/orld Wide Web

The first notable web browser, which went on to inspire Microsoft's Internet Explorer and also Mozilla Firefox, was called Mosiac, and was released on January 23, 1993. It was the first  revolutionary web browser, and the first web browser to successfully create a usable interface for navigating websites. While the browser was discontinued in 1997, Google Chrome is the only web browser to not have confirmed taking some inspiration from Mosiac.
This browser started the internet craze, which first started in the 1990's. More information can be found here: https://en.wikipedia.org/wiki/Mosaic_(web_browser)#/media/File:NCSA_Mosaic.PNG

The internet, also known as the world wide web, is an almost incalculably large number of computer networks which share information with each other, and in the case of websites, other users as well. It is the websites that you use via your web browser, and any electronic service that you use that does not store information directly on your computer or device.

According to http://www.govtech.com/e-government/Who-Invented-the-Internet.html, who actually invented the internet is at least somewhat unclear. Ideas referring something revolving the interment can go back to at least the 1940's if not further, but web browsers and being able to surf websites on computers first came around in about 1993.
Today, the internet boasts several different ways of communication, such as email, social media, and instant messaging. It also boasts several different ways of pushing around information, such as blogs, podcasts, and wikis.

Email and Social Media are tow ways of communicating over the internet. What they are is a method of sending messages or files / information over the internet to other devices or computers, via email address providers (such as Gmail, Outlook, Yahoo Mail, etc). Social Media, such as websites like Facebook, Twitter, Instagram, is a tool for publicly sharing information with large amounts of people at once, weather it be a friends list, public post, etc. Some social media sites, such as Facebook, also allow for personal messaging.

Email and social media share some ideas; they allow users to message each other and in some cases (such as Facebook) send attachments.
While email services such as Yahoo email and Microsoft's Hotmail (which has since been re titled Outlook) first became popular in 1996-1997, according to http://www.inventorofemail.com/history_of_email.asp, the first email was sent in 1978 in Newark, New Jersery.

Wikis are somewhat like social media, with Wikipedia being the most famous one, are websites / online services which allow groups of users to update information on a certain subject or topic. They are web services where more than one person contributes to an article.

According to  https://en.wikipedia.org/wiki/History_of_wikis, WikiWikiWeb, which was one of the first major wikis was started in 1994. It was started by Ward Cunningham, and ran on c2.com

Blogs share roughly the same idea as wikis, but there is one key difference. Blogs are generally one person posting on a thread, as opposed to several people. A history of blogging can go back quite a way as well. According to https://www.webdesignerdepot.com/2011/03/a-brief-history-of-blogging/, the term can also be related to at least back to 1997.

Streaming media can be done in several different ways, from recording audio and implementing it on a website or service, or recording a video, saving the video, and uploading it to a website such as YouTube. Another popular method of steaming media is what is called live stream, which is live filming yourself or what your doing and broadcasting it as it is happening, as opposed to saving the video when it's over. According to https://www.theguardian.com/media-network/media-network-blog/2013/mar/01/history-streaming-future-connected-tv, "On 5 September 1995, ESPN SportsZone streamed a live radio broadcast of a baseball game between the Seattle Mariners and the New York Yankees to thousands of its subscribers worldwide using cutting-edge technology developed by a Seattle-based startup company named Progressive Networks. It was the world's first live streaming event." While there may have been attempts before then, this would imply that this was the one of the first times media was streamed live.

E-commerce and M-commerce are the same thing. They are both buying (or selling) products and services via online methods. The only difference is that E-commerce  is doing this via a computer on the internet, where as M-commerce is doing it via cellular devices. According to https://www.simicart.com/blog/differences-between-e-commerce-and-m-commerce/, the term E-commerce was invented in the 1970's and M-commerce in the 1990's. As of 2017, roughly 97% of businesses which sell merchandise have methods of buying there products online, weather that be via Amazon, eBay, or their own company website. As of 2017, over 357 million products have been sold via e-commerce and m-commerce, and that is via Amazon.com alone.
