Measurement

I worked for a television station when the Internet took off.
I demonstrated streaming video to a salesperson, and then showed them the statistics file.
The salesperson recoiled in horror, like a vampire faced with a cross made out of garlic.
“What’s wrong?” I asked.
“The exact figures?” they asked. “No corrections?”
“Exact,” I said. “Just like Nielsen numbers.”
“But Nielsen corrects those numbers,” she said.
“Corrects?” I asked.
“Fudges,” she admitted. “If the advertisers knew the real numbers, they’d freak out.”
“So did you. Why do we use them if they’re wrong?”
“Because they’re the wrong we agree on.”
