Twisted answer: A Benz pulls up to the entrance and a man gets out and runs to open the door. Out steps an aged but refined model known as MS IE8. She’s obviously due anytime and rumor has it the tradition will carry on and she will be named MS IE9. Behind the piece of work is several generations of mothers. MS IE5, MS IE6, and MS IE7 are all there. Makes a Mother proud. They walk to the theater entrance and tell the doorman their name and are escorted straight in. Next, A big Lincoln Navigator rolls up and a big woman known as Opera climbs out and rolls up to the doorman and announces herself. She too is escorted right in. Next a Ford pickup screeches to a halt an out comes a burly fellow named Mozilla with a very beautiful item beside him known as Firefoxy. They prance up and tell the doorman their names and are escorted in. Finally, a Jeep pulls up and out steps a refined man that walks to the doorman and says “Hello, My name is Ibe Google, IV”. The doorman says, “I’m sorry sir, but your name is not
on the list.I can’t let you in.” Disappointed but determined to attend the event, Ibe steps back and watches a few lesser known attendees allowed in. This gets him to thinking about his cousin Im Chrome who is welcome everywhere. He gets back into his Jeep and pulls around the corner, takes off his coat, reverses it, and puts it back on. He walks back around the corner and up to the doorman. He says “Hello, my name is Im Chrome.” The doorman says “Welcome Sir. Come right this way.” The moral of the story is it’s not who you are but who you can say you are.

Simple answer: All brands of internet browsers applications (User Agent) identify themselves (in a string of characters sent) to the service providers (Web Servers, etc.) during communications.
A handshake so to speak. this allows the service to make accommodations to the services provided as needed, such as to disallow use of that service. Google TV could easily can try to first identify itself in the User Agent string as “Google TV” and if services were disallowed, it could repeat the attempt with a User Agent string of “Google Chrome” and then be allowed access. Same application but masquerading as a Google Chrome browser application (User Agent).
