In context

We hold 18 other video game industry companies founded in the 1970s. 13 of them have closed, after a median of 23 years, and 5 have no closure recorded.

Counted across this directory, from founding and closing years in public records. Medians cover only companies whose closure is recorded; a company with no closure date may have quietly ceased without the record catching it.
