Happy birthday, Twitter!

Twitter is gearing up for its fifth birthday, with founder and co-chairman Jack Dorsey posting a series of messages detailing the humble beginnings of the micro-blogging site.

The first tweet was published on March 21st 2006, but years of planning went into creating the hugely successful social media site, which was originally targeted at mobile users and programmed in only five days.

According to Dorsey – tweeting as @jack – the site was originally titled '' and then 'twttr' with no vowels.

The eventual site name as it is known today came from the Oxford English dictionary and manager Noah Glass, who defined Twitter as "a short inconsequential burst of information, chirps from birds".

Dorsey has shared several early designs for the site – including the original idea for Twitter, drawn on a notepad in 2001 – via his Twitter account in celebration of the milestone anniversary.

It is thought that Twitter is now worth approximately $10 billion and has rapidly-growing revenues.

Market intelligence and statistics provider e-marketer suggested that Twitter's revenue for 2011 will be $150 million, up from $45 million last year.

It has previously been reported that search engine giant Google has designs on Twitter and the two online firms reportedly held preliminary talks in February.
