Second, television networks' viewership rating fraud: once a contract nears expiration, the network, in order to maximize benefits in renewal negotiations, inevitably fabricates viewership data. This is almost an open secret in the industry. However, if BT has its own network nearby, it can use its own viewership data to estimate how much is fabricated in the other party's data, easily exposing their lies and strengthening its negotiating position. That's why I own a network in the local area—I can simply not renew the contract and slowly look for new partners if needed. After all, a dip in viewership is still within an acceptable range.
