Now that TV's are computers, it takes them almost that long to boot up.
And the horizontal and vertical hold buttons that always had to be adjusted......
With the old time tee vee we had the rabbit ears. ALWAYS a challenge.
And remember the old test patterns? Do remember the one most often used was an Indian in his headdress. And before signing off for the evening the station would ALWAYS -STRESS-ALWAYS play The Star Spangled banner with images of our military being shown while the anthem was being played.
Not only did the take five minutes to warm up, they only came in black and white. At midnight, the TV stations ended their broadcast for the day by playing the National Anthem, then nothing but a test pattern on the tv until 6 in the morning when they played the National Anthem again and start the programs for the day.
