Happy birthday, TV! Celebrating 90 years of television

SAN FRANCISCO (KGO) -- Happy birthday to the television! That bright box we all love to stare at turns 90 years old today.

It was on September 7, 1927, that 21-year-old Philo Farnsworth transmitted the first all-electronic television image. Farnsworth worked out of his "Green Street Lab" in San Francisco, a site designated as a California Registered Historic Landmark.

Farnsworth patented his designs and started a revolution that is still with us today.
