I think the main reason is simple, like the idea at the programme’s heart. Time Team is a true reality show: it reflects the real world of a true-life excavation. Thousands of smaller versions of Time Team happen every year in the world of commercial archaeology. These rapid, often small-scale excavations are known as assessments and they’re the first stage that any developer has to go through ahead of a major scheme, such as a housing estate, new road or gravel pit. After that first investigation, there’s often a larger-scale rescue excavation which focuses on areas of interest revealed by the assessment. So, claims often made by some hostile academics, that our three-day format is somehow false, are simply not true.
