(Reuters) - Twitter Inc reported its slowest growth in quarterly revenue since going public in 2013 as the company faces intensifying competition from fast-growing competitors such as Snapchat and Instagram. Twitter's user base, however, modestly increased to 313 million average monthly active users in the second quarter from 310 million in the first quarter. The company, which has been struggling with stagnating user growth and lower spending by advertisers, is doubling down on efforts to attract users.
The U.S. Food and Drug Administration opened the door on Tuesday to a change in its blood donor deferral recommendations, which currently prohibit donations from gay men for a year following their last sexual encounter in order to reduce the risk of transmitting HIV, the virus that causes AIDS. In December the FDA overturned a 30-year ban on all blood donations from men who have sex with men, saying the change was based on science showing an indefinite ban was not necessary to prevent transmission of the human immunodeficiency virus. The FDA is now signaling it may go further.
