Talk:Tom Baker stars in John Lloyd's lost Doctor Who adventure, The Doomsday Contract (webcast)

Validity?
Big Finish's analysis of this webcast refers to it as a trailer 3 times. As the policy currently stands, T:VS states that trailers aren't valid sources. Furthermore, it's referred to as a promo in that article, and T:VS also states that commercials/advertisements can't be valid. Regardless of whether it had been referred to as a promo, it clearly is an advertisement. As a result, I struggle to understand why this is a valid source under current policy.

 * I created the article as valid as the YouTube upload itself did not refer to it as a trailer. 📯 📂 08:05, 26 April 2021 (UTC)
