X (Twitter)
Also known as: Twitter, Tweet, X platform, Elon Musk Twitter, X Premium
X, formerly Twitter, is a social media platform centred on short-form public posts (280 characters for free accounts, much longer for paying subscribers) where users follow accounts, engage with breaking news, public discourse, and trending topics.
It was founded in 2006 and became the defining platform for real-time public conversation: used by journalists, politicians, celebrities, scientists, and brands for instant communication and commentary. Elon Musk acquired Twitter for $44 billion in October 2022 and rebranded it to X in July 2023, also implementing significant structural changes including paid verification (X Premium), API access restrictions, and content moderation policy changes.
X (Twitter), explained at three levels
At home
X (formerly Twitter) is a platform where you post short messages (called posts or tweets) that are public by default, although X now asks visitors to log in before browsing most of it. You follow accounts you find interesting (news organizations, politicians, celebrities, experts, friends) and their posts appear in your timeline. You can reply to posts, share others' posts (repost), and like them. X is known for real-time news and commentary: during breaking events, X is often where information spreads first before traditional news sources catch up.
At work
X is used professionally for following industry news, engaging with journalists and thought leaders, and building a public presence around expertise. Many industries have active X communities: tech, journalism, finance, healthcare, and policy. A well-maintained X presence can be valuable for personal brand building (sharing insights, engaging in industry conversations) and for businesses that benefit from real-time customer interaction or public communications. However, X's usage has declined among some professional segments following the Musk acquisition.
At home
X's timeline can be set to 'For You' (algorithmic: showing content the algorithm thinks you'll engage with, including from accounts you don't follow) or 'Following' (chronological posts from accounts you follow). The For You feed amplifies virality: posts that get significant engagement quickly spread to non-followers. Hashtags remain a discovery mechanism but are less central than in Twitter's early years. Lists let you curate a focused feed from specific accounts, useful for following a specific topic or community without algorithm interference.
At work
X Premium (formerly Twitter Blue) offers paid features: longer posts, post editing, fewer ads, higher reply priority (Premium posts shown first), and the blue checkmark (which now indicates payment, not identity verification). The loss of meaningful verification (the previous system confirmed identity for public figures) has made it harder to distinguish verified expert accounts from paid imposters. For brand communications and PR, X remains relevant for crisis communication, product announcements, and engaging journalists, though its reach has fragmented as users migrated to Threads, Bluesky, and LinkedIn.
At home
X's API access restrictions post-2022 had significant downstream effects: research on social media misinformation, platform behaviour, and election influence became much harder as the academic research API was removed or heavily restricted. Third-party clients (Tweetbot, Twitterrific) were shut out by API pricing changes. The data journalism and computational social science communities that had built research programs around Twitter's API had to pivot to other platforms or discontinue lines of research. This was a material loss to the public's ability to study social media at scale.
At work
From a brand risk perspective, X's content moderation changes post-acquisition increased brand safety concerns: major advertisers (Apple, Disney, IBM, and many others) paused advertising spending when their ads appeared alongside extremist content. X sued several of these advertisers, creating additional reputational risk for brands advertising on the platform. Brand safety tools (keyword exclusion lists, content category blocking) exist but have been less effective post-acquisition. Brands with conservative communication policies have generally reduced X advertising spend and shifted to other platforms.
Real-world examples
At home
Jerome used X primarily to follow breaking technology news and developer community discussions. He followed accounts of developers he respected, tech journalists, and company engineering blogs. During major product launches or security incidents, his X timeline was hours ahead of mainstream news. He also used X to share blog posts he wrote, which occasionally got picked up by influential accounts in the tech community and drove traffic to his site.
At work
Lena was a communications director who used X as a primary channel for monitoring sentiment about her company and responding to customer issues that went public. She set up Tweetdeck (now X Pro) columns for brand mentions, competitor mentions, and relevant industry keywords, monitoring in real time. During a product recall, the company's X account responded publicly to concerned customers within minutes, which journalists covering the story cited as an example of transparent crisis communication.
Common confusions
- Many people assume the blue checkmark on X still means an account is verified as authentic — Since Elon Musk's acquisition and the introduction of X Premium, the blue checkmark simply means the account pays for an X Premium subscription (prices vary by tier and country). It no longer verifies that the account belongs to the person, organization, or public figure it claims to be. Gold checkmarks indicate verified organizations; grey checkmarks indicate government accounts. The loss of identity-based verification has made impersonation and imposters harder to detect on the platform.
- Some brands assume X is no longer relevant and have abandoned it entirely — X retains a disproportionate influence on news cycles relative to its user numbers: journalists, politicians, and media figures remain heavily active, meaning stories that originate or amplify on X still reach mainstream media. For brands in tech, finance, media, and policy, X remains a relevant monitoring and response channel even if advertising investment has declined. Abandoning X monitoring entirely means missing conversations that can influence public narrative about a brand, even if the brand isn't actively participating.
For analysts
When a client asks about X (Twitter) as part of their social media strategy, the honest assessment is: X is worth monitoring for brand mentions and industry conversation regardless of whether you actively post, because conversations there influence media coverage. Active brand presence on X is most valuable for companies in tech, finance, media, and policy where X remains a professional community hub. For consumer brands primarily advertising on social media, the migration of advertiser trust and audience attention to other platforms makes X a lower priority than it was pre-2022.
History & origin
Jack Dorsey, Biz Stone, Noah Glass, and Evan Williams created Twitter in 2006, with the 140-character limit inspired by SMS message length. Early adopters included journalists and tech insiders who made it the platform for breaking news. Twitter became indispensable during major events: the Arab Spring (2010-2012), when Twitter enabled real-time reporting from protest movements; various elections, where it became the primary channel for political discourse; and crises, where the hashtag became a coordinating mechanism. Twitter's chronic profitability struggles led to multiple acquisition rumors before Elon Musk's hostile buyout ($44B) in October 2022. Post-acquisition: Musk laid off approximately 80% of staff, removed many trust and safety employees, reinstated suspended accounts (including those previously banned for policy violations), introduced X Premium (paid blue checkmark subscription), and restricted API access significantly: affecting third-party clients and researchers. The rebranding to X (July 2023) attempted to reposition the platform as a broader 'everything app.'
