A new era of Doctor Who has kicked off with the launch of the Whoniverse on BBC iPlayer. The Whoniverse banner covers all Doctor Who content, from the main show to spinoffs and behind-the-scenes specials. The first original series to be released within the Whoniverse is Tales of the TARDIS, a Doctor Who companion series that sees past Doctors and companions returning in a "memory TARDIS" in order to recount their old adventures. The first season consists of six episodes, all featuring characters and stories from the classic series.
