TV Licence inspectors claim they can determine if individuals are watching TV and even identify the channel, although their methods remain unclear. Historically, they used technology to detect signals emitted by TVs, but recent enforcement has decreased with the rise of broadband. Inspectors are often seen as salespeople on commission, and there are concerns about their lack of transparency regarding detection methods. The BBC is funded through TV licenses, which some argue is difficult to enforce in the current digital landscape. Overall, the discussion highlights the ongoing debate about the necessity and fairness of the TV licensing system in the UK.
