I LOVE Spongebob Squarepants! It's my favourite show. I tune in to Bikini Bottom at least once a day.
Haha, yeah it's a pretty funny show. There's also a surprising amount of hidden adult humor for a kids show!
I think it's popular with a lot of people - kids and adults alike. Apparently it made 13 BILLION dollars in merchandise revenue for Nickelodeon last year. That's crazy! 
Wow! Sign me up... those companies really know how to market their products. I wonder how this will change in the future. It seems like more and more people are using streaming sites like Newflix.
I am not sure! Good thing they named him Spongebob. I don't know if his original concept name of Spongeboy Ahoy would have sold as well.
