Ethereal is a really nice application. However, it has it's limits.
RMON (see RFC 3577) or Remote Monitoring is a set of SNMP MIBs which you allow you to gather traffic information (including packet captures) from network elements itself. You do not need to have a computer to run ethereal, snoop or tcpdump.
The switch/router/probe will collect the info for you, automatically.
Virtually all switches support (mini-)RMON. Furthermore you have (full) RMON probes which you can install at various places in the network.
The flexibility of RMON probes is much larger then ethereal. However, I often use ethereal to look at the packet captured using RMON.

I am not sure which channels your are talking about. I'm in Belgium and we have Belgian, Dutch, French, German, Spanish, Britisch and Italian channels over here (and some US channels like MTV, CNN,...).
I just had a look at all these European channels. Although 2 out of 3 carry a logo (1 out of 3 does not!) there are all of the time white and transparent. Most of the Belgian station even remove the logo during movies and only put them there during game shows, news broadcasts,...
Off course, I might be in the wrong European country;)
I would say that this depends strongly from country to country in Europe. It is definetly not a European issue.
