Those with the Virgin Media Tivo box may have seen recommendations for similar shows based on our viewing preferences such as our recordings in MY SHOWS etc.
Another point is that both Sky + HD and Virgin Media boxes allow us to do a keyword search for the actor or actress or programme title etc, so maybe we find similar programmes that way.
Furthermore, we now have more access to Catchup TV episodes for various shows and series and may have video on demand access as well. Sky + Anytime is now available with any Broadband ISP and has to be authorised to do this, see forum search for this info.
Inbetweeners is an American Teen series, so that category helps to find similar series. Sky is more likely to get US shows and Virgin Media packages have to be checked to find out which channels these appear on and even then we check if available on Freeview as well, if not now, then perhaps next year.
Please note the Inbetweeners has been created as the UK series as explained here:
