It's been more than a year since "Pokemon Go" took the world by storm, getting people to wander outside and look for virtual monsters with their smartphones.
The game became a social phenomenon, with adults and children gathering in parks and public areas to train their Pokemon. The fad is still going strong, with new characters and upgrades being added regularly. Though down from its peak, more than 65 million people still use the app each month. In the United States, the game is among the 20 most-lucrative apps this year, holding the top spot for about a week in July.
For the companies behind "Pokemon Go" — Niantic Inc., Pokemon Co. and Nintendo Co. — the game has been an earnings bonanza, with revenue estimates ranging from $1.5 billion to $2 billion. Nintendo has reported ¥23.6 billion ($215 million) in income from equity stakes in other companies, the bulk of which came from its partial ownership of the Pokemon company.
