Two likely reasons. First, the previous form factor didn't fit in all TVs, so they had to include a tiny HDMI extender cable; this form factor has built-in tolerance for tight fits. Second, the new form factor allows more room for hardware bits and heat dissipation.

Also probably because some television sets can block wifi signals up close. I had a weak wifi connection on mine and a 3 ft hdmi extender fixed it (which was probably overkill).

I had this as well. Took me a while to figure out it was my Chromecast. When I watch TV I basically have to turn of my Chromecast because of the otherwise interference it causes.
