X

A social network for short public posts: a business uses it to show its product, answer customers, and collect followers who may later become buyers.

What X is

Written from its maker's own pages, read on 28 October 2026.

X, formerly called Twitter, is a social network for short public posts, run by X Corp. People follow accounts that interest them, and businesses use it to reach people with their own posts and with paid ads.

A post may contain text, links, photos, GIFs and videos. A regular post has up to 280 characters; subscribers can write longer posts of up to 4,000 characters. Each user has two timelines. Following shows posts only from the accounts the user follows. The other, a recommendation timeline, mixes those posts with recommended posts, which X selects with signals such as how popular a post is and how people in the user's network interact with it. Other users can reply to a post, repost it or mention an account in their own posts. For businesses, X Ads shows paid posts to a chosen audience, with geographic targeting and a budget that the advertiser sets.

Posting is free. X Premium, now part of The X Subscription, is an optional paid plan with extra features, and ads are paid from the advertiser's budget.
