your life with friends through a series of pictures. You

just need to snap a photo with your mobile phone,then

choose a filter to transform the image into a memory to

keep around forever ! You can do it at once. In real time !

Kevin Systrom and Mike Krieger are the CEOs and

co-founders of Instagram .

Mr.Systrom and Mr.Krieger always loved taking pic-

-tures so they assumed taking interesting photos re-

-quired sophisticated cameras and a couple of years

of art school.

However,as mobile phone cameras improved so much

and so fast,they decided to challenge that assumption.

They created the Instagram to solve 3 simple problems:

1)Instagram great looking filters transform mediocre/poor

photos into professional -looking snapshots.

2)Sharing the photos on multiple platform or services with-

-out too much trouble.

3)Instagram optimized the exprience of photographing to be

fast and efficient.

Consequently, Instagram became very popular on the

spur of the moment because nowadays most people can

-not wait too long to share photos and information on

any media ,can they ? The faster the better !

Obs : at once and right away are synonyms for immedia-

-tely;right now;straight away;on-the-spot ;on the spur of

the moment.
