Twitter turned ten today with the social media site having hosted some of the biggest movements of the last decade, although uncertainty hangs over its future.
The site is struggling to attract new users, has seen share prices tumble and faces continued questions over how it handles abuse, but can still lay claim to some of social media's biggest moments of the last decade.
The very first tweet on the network was sent on this day ten years ago by co-founder Jack Dorsey.

Five hundred million tweets are now sent every day, with 200 billion posted every year and hashtags such as #JeSuisParis in the wake of the November terrorist attacks in the French capital dominating international debate online.
Last year's marriage referendum garnered particular traction on the social media network, with the #HomeToVote hashtag documenting the journeys people made to the polling stations.
However, issues have continued to plague Twitter, particularly surrounding abuse - something actor Stephen Fry cited when he quit Twitter last month.
He described its decline from "a secret bathing-pool in a magical glade" to a stagnant pool that is "frothy with scum, clogged with weeds and littered with broken glass, sharp rocks and slimy rubbish", adding that he felt the site had become a "stalking ground".
Uncertainty remains over the future of the network, with speculation continuing over possible plans by the firm to remove the site's signature 140-character limit, despite calls to resist from the majority of users.
The site has also made moves away from the reverse chronological order in which tweets traditionally appeared - a move that has not been popular among some users.
