"It was mainly the porn industry that really pushed home VCR technology into common usage"

And every other entertainment medium of the last century!

:-)

Home movie cameras... moving pictures in general... VCRs... Digital recorders...

The porn industry is ALWAYS on the cutting edge of entertainment tech...

Know why DVD won the battle vs VCDs??? Cause the makers of VCDs said they wouldn't put porn on them...

Or you would have been able to watch movies on your PCs without a DVD drive...
