In European news both events received significant coverage. Local news trumps global. I am sure in Greece the Messenia migrant boat disaster got more coverage than Titan. That said, the big factor is how sadly common migrant boat disasters are (just like liquid gas exploding in a restaurant in China and killing 10+ people, happened yesterday). Carbon fiber submersible on the way to Titanic containing cocky inventor, plus billionaire, plus kid hits so many spots for news cycle.
