Concept: YouTube
Youtube is a video-sharing website, created by three former PayPal employees in February 2005, on which users can upload, view and share videos. The company is based in San Bruno, California, and uses Adobe Flash Video and HTML5 technology to display a wide variety of user-generated video content, including movie clips, TV clips, and music videos, as well as amateur content such as video blogging and short original videos.
Most of the content on YouTube has been uploaded by individuals, although media corporations including CBS, the BBC, VEVO, Hulu, and other organizations offer some of their material via the site, as part of the YouTube partnership program. Unregistered users can watch videos, while registered users can upload an unlimited number of videos. Videos considered to contain potentially offensive content are available only to registered users at least 18 years old.
YouTube is a free online video service that allows anyone to view, upload and share videos that can be viewed by anyone else in the world with an internet connection.

Concept: Flickr
Flickr (stylized as flickr) is an image hosting and video hosting website, web services suite, and online community that was created by Ludicorp in 2004 and acquired by Yahoo! in 2005. In addition to being a popular website for users to share and embed personal photographs, the service is widely used by bloggers to host images that they embed in blogs and social media. Yahoo reported in June 2011 that Flickr had a total of 51 million registered members and 80 million unique visitors. In August 2011 the site reported that it was hosting more than 6 billion images and this number continues to grow steadily according to reporting sources. Photos and videos can be accessed from Flickr without the need to register an account but an account must be made in order to upload content onto the website. Registering an account also allows users to create a profile page containing photos and videos that the user has uploaded and also grants the ability to add another Flickr user as a contact. For mobile users, Flickr has an official app for iOS, Android, and Windows Phone 7 operating systems.
Flickr
is an online photo management and sharing application. Its primary
goals are to help people make photos available to those who matter to
them, and to enable new ways of organizing pictures. You can join
Flicker for free and begin sharing images immediately. Pro accounts are
available for those who want to add and display high volumes of photos.
Features of Flickr:
1. Accounts
Flickr offers two types of accounts, Free and Pro. Free account users are allowed to upload 300 MB of images and two videos per month. If a free user has more than 200 photos on the site, they will only be able to see the most recent 200 in their photostream. The other photos that were uploaded are still stored on the site and links to these images in blog posts remain active. Free users can also contribute any of their photos to a maximum of 10 photo pools.
Pro accounts allow users to upload an unlimited number of images and videos every month and receive unlimited bandwidth and storage. Photos may be placed in up to 60 group pools, and Pro account users receive ad-free browsing and have access to account statistics. As soon as a Pro account expires, it reverts to the restrictions of a free account, including Flickr's right to delete an account that is "inactive for 90 consecutive days". Flickr may delete a Pro account without giving any reason nor warning to the account's owner.
2. Groups
Groups can be started by any member of Flickr. The creator of the Flickr group is given the ability to monitor and set restrictions for the group. Groups are used as a way to communicate with fellow members of Flickr around common photography interests. By choosing to follow groups, recent uploads of the group will sometimes appear on a user's homepage when they log on.
3. Organization
Flickr asks photo submitters to organize images using tags (a form of metadata), which enable searchers to find images related to particular topics, such as place names or subject matter. Flickr was also an early website to implement tag clouds, which provide access to images tagged with the most popular keywords. Because of its support for tags, Flickr has been cited as a prime example of effective use of folksonomy, although Thomas Vander Wal suggested that Flickr is not the best example.
4. Organizr
Organizr is a web application for organizing photos within a Flickr account that can be accessed through the Flickr interface. It allows users to modify tags, descriptions, and set groupings, and to place photos on a world map (a feature provided in conjunction with Yahoo! Maps). It uses Ajax to emulate the look, feel, and quick functionality of desktop-based photo-management applications, such as Google's Picasa and F-Spot. Users can select and apply changes to multiple photos at a time, making it a better tool for batch editing than the standard Flickr interface.
5. Picnik
Flickr had a partnership with the Picnik online photo-editing application that included a reduced-feature version of Picnik built into Flickr as a default photo editor. From Thursday 5 April 2012, Flickr has replaced Picnik with Aviary as its default photo editor.
6. Access control
Flickr provides both private and public image storage. A user uploading an image can set privacy controls that determine who can view the image. A photo can be flagged as either public or private. Private images are visible by default only to the uploader, but they can also be marked as viewable by friends and/or family. Privacy settings also can be decided by adding photographs from a user's photostream to a "group pool". If a group is private all the members of that group can see the photo. If a group is public the photo becomes public as well.
7. Interaction and compatibility
Flickr's functionality includes RSS and Atom feeds and an API that enables independent programmers to expand its services. This includes a large number of third-party Greasemonkey scripts which enhance and extend the functionality of the Flickr site. In 2006 Flickr was the second most Greasemonkey-extended site.
The core functionality of the site relies on standard HTML and HTTP features, allowing for wide compatibility among platforms and browsers. Organizr uses Ajax, with which most modern browsers are compliant, and most of Flickr's other text-editing and tagging interfaces also possess Ajax functionality.
Images can be posted to the user's photostream via email attachments, enabling direct uploads from many camera phones and applications with email capabilities.
8. Filtering
In March 2007 Flickr added new content filtering controls that let members specify by default what types of images they generally upload (photo, art/illustration, or screenshot) and how "safe" (i.e., unlikely to offend others) their images are, as well as specify that information for specific images individually. In addition, users can specify the same criteria when searching for images. There are some restrictions on searches for certain types of users: non-members must always use SafeSearch, which omits images noted as potentially offensive, while members whose Yahoo! accounts indicate that they are underage may use SafeSearch or moderate SafeSearch, but cannot turn SafeSearch off completely.
9. Licensing
Flickr offers users the ability to either release their images under certain common usage licenses or label them as "all rights reserved". The licensing options primarily include the Creative Commons 2.0 attribution-based and minor content-control licenses - although jurisdiction and version-specific licenses cannot be selected. As with "tags", the site allows easy searching of only those images that fall under a specific license.
10. Map sources
In addition to using commercial mapping data, Flickr now uses OpenStreetMap mapping for various cities; this began with Beijing during the run-up to the 2008 Olympic games. As of October 2008, this is used for Baghdad, Beijing, Kabul, Sydney, and Tokyo.
11. Account-undelete option
In May 2011 Flickr added an option to easily reverse an account termination. This action was motivated by a very public accidental deletion of a Flickr user's account, and its very protracted restoration.
