Twitter began with 140–character text messaging, has evolved over the past decade, from text to a rich canvas featuring photos, videos, hashtags, Vines, and more.
Additionally, tweets also now offer abilities such as poll your community, GIFs, Periscope broadcasts.
As of now, twitter counts spaces, media attachements etc. all towards 140–character limit, but that's going to change starting on September 19 —as twitter will be simplifying tweets including how they counts 140 characters, the microblogging site says that "@names in replies and media attachments" will no longer "use up" valuable characters.
Twitter notes, since this update has a significant impact on tweets, developers must ensure to update their products built using Twitter's API before the changes goes online.
In addition, the microblogging company also exploring ways to get more out of the tweets—"all without compromising the unique brevity and speed."
Here's what will change:
After the changes go online, while you reply @names will no longer count toward 140-character count.
This will make having conversations on Twitter easier and more straightforward, no more penny-pinching your words to ensure they reach the whole group.
Also, media attachments like photos, GIFs, videos, polls, or Quote Tweets, will no longer count as characters.
Twitter says it'll also enable retweet button on your own Tweets, "so you can easily Retweet or Quote Tweet yourself."
Lastly, you will no longer have to use the ".@" convention, because new tweets that begin with a username will reach all your followers. If you want a reply to be seen by all your followers, "you will be able to Retweet it to signal that you intend for it to be viewed more broadly," twitter writes.
