NEW YORK (AP) — Twitter is once again attempting to launch its premium service a month after a previous attempt failed. The social media company said it would let users buy subscriptions to Twitter Blue to get a blue checkmark and access special features starting Monday. The blue checkmark was originally given to companies, celebrities, government entities and journalists verified by the platform. After Elon Musk bought Twitter for $44 billion in October he launched a service granting blue checks to anyone willing to pay $8 a month. But it was inundated by imposter accounts, so Twitter suspended the service.
