Twitter share price rises as Google and Salesforce express interest in its purchase

Twitter shares rose by more than 20% to $22.46 per share today on the report of sales talks. And it seems that Google and Salesforce are in the forefront of many technology companies that are interested in buying the social media company.
Twitter has been the subject of takeover talks for some time and Google had earlier expressed its intention to buy the company but nothing happened.
Twitter’s board of directors is said to be largely desirous of a deal, according to people close to the situation, but no sale is imminent.
Twitter currently has a market value of nearly $16 billion.
Twitter has been struggling to generate revenue growth and profits despite its 313 million average monthly active users and being a usual source of breaking news.
