Will Zoom's $15bn purchase help it expand?

Video platform Zoom Video Communications has become a "household name" during the pandemic, say Rob McLean and Michelle Toh on CNN. Just two years ago it was valued at $16bn, but its market capitalisation has since soared above $100bn after millions of people turned to it for remote videoconferencing during lockdown. Now vaccines are allowing more people to get back to the office, so it needs to "find new avenues of growth".
