The web 2.0 was referring to the social and content rich web.
Mobile 2.0 is a common term that is used to describe many things.
It was first referring to the contextual aware network with M2M (Machine-to-Machine) direct communication.
Now it is mostly use to describe the mobile interface of the Web 2.0.
The mobile is usually used as an access channel to the web-based applications and services (there are some pure mobile services but they are too significant).
The Mobile device is a multimedia creation and consumption device for several years now.
It is only logical that the mobile device will take a part in the content creation for the Web 2.0 / Mobile 2.0 services.
Many services (like flickr) provided the means to upload to the web content from your device.
It was usually done with pictures and content that only requires a low bandwidth.
Others like many facebook applications, used a mailing mechanism with MMS (Multimedia Messaging Services) but MMS only supports files up to 300Kb so no good video of over 10 seconds can be sent and it is not immediate (just like in mail).
All solutions lacked immediacy (like you can create an immediate content with your webcam).
Qik and Flixwagon are two competitors who are battling for the title (And no, I did not forget Kyte).
Until today the battle was more or less around “who supports more devices” nevertheless, Flixwagon’s recent announcement on its partnership with Nokia may change the rules.
Nokia, with its services portal (OVI) intends to create one place where all Nokia users could upload all of their content.
With the help of Flixwagon, Nokia hopes to create the “mobile youtube” but only for Nokia users.
Qik from the other hand is still focusing on bringing the service to any device, smartphones and low-end devices as well according its latest announcement.
The new Nokia 5800 is coming with a download catalog where Qik application can be found that’s not much but it indeed is a good sign for Qik.
Both Qik and Flixwagon have yet a long way to go, until live broadcasting will turn from a niche product and go to the mainstream.
