As you may (or may not!) know, Barcelona is the capital city of a small nation called CATALUNYA --'Catalonia' in English :))
The National Catalan broadcaster TV3 has recently launched (sep2015) a new weekly documentary series called "Catalunya Experience" in which a popular Catalan TV presenter, Ivana, takes a set of different guests from all over the world in each program on a one week's journey through Catalonia to 'experience' -hence the title!- our little country as one of us. This approach allows the guests not only to see incredible attractions and magnificent landscapes but also to participate in folk activities and mingle with Catalan people in our festivities and traditions. The aim is to present Catalonia to the guests in a more intimate manner.
For those willing to plan a 'less touristy' visit to Catalonia, these series are a good starting point to get ideas. The chapters are (partially) in English and can be seen in the PROGRAM'S WEBSITE (in Catalan, use Google Translate!) or directly in youtube
After that, these other websites can also be useful to broaden your planning:
Catalonia Tourism Board | Videos | Costa Brava | Girona | Tarragona | Costa Daurada | Counties of the Ebre river area | Val d'Aran-Pyrenees | Lleida
... and specifically for Barcelona:
Barcelona Tourism Board | Videos | Timeout Barcelona | My Barcelona
There are plenty other informational sites but these are some popular ones to get YOU started. Actually, almost each county and city in Catalonia has its own tourism website with information about local features, attractions, activities and hotels/restaurants so if you're interested in a particular area/city try googling its name and "tourism" or "turisme".
Enjoy!
