Twitter isn't limiting its livestreaming to major sporting events. The social network has revealed that it will stream both the Democratic and Republican national conventions, which respectively start on July 25th and July 18th. The coverage (technically provided by CBSN) will be available through both the web and Twitter's official mobile apps, and won't require an account to start watching.
Like it or not, the events themselves may well be foregone conclusions when both Hillary Clinton and Donald Trump have enough delegates to clinch their nominations. However, this is still a big deal. Many people are likely to turn to Twitter to comment on the conventions -- now, they can watch it in the same place. Twitter is no doubt using this to reel in some sorely needed new users, but it'll help everyone if it widens exposure to the electoral process.
