Canon
Jim and Pam's friendship had caught the attention of the documentary crew filming the Dunder-Mifflin Scranton branch right from the beginning. Their constant playfulness and quick, adorable exchanges hinted that they may have deeper feelings for one another.

Pre-Series
The first moment Jim knew he liked Pam was when she told him to forever remember the moment before he met his future desk-mate, Dwight who Jim would eventually share a frenemy-like relationship with. Jim also claims that his best "first date" was with Pam as they shared many things in common. This only lasted until the moment Jim realized that Pam was engaged to Roy and their lunch was just between friends.

Later in the series, Pam admits to Jim that she knew she liked him when he made a funny comment on her mixed berry yogurt which had expired. Unfortunately, at the time she mostly denied her true feelings for Jim and only saw him as her best friend for many years because she was still engaged to Roy.

Children
Jim and Pam have two children together over the course of the series. Their first child is their daughter; Cecelia Marie Halpert, born on 4th March 2010. Their second child is their son; Phillip Halpert, who was born on 5th December 2011. Phillip was named after Pam's grandfather as she promised him she would name her first son after him.

Fanon
Jim and Pam are considered one of the greatest television couples of all time. They are ranked number one as the most iconic TV couple of the 2000s as well as one of the greatest modern sitcom romances and "Will They, Won't They" couples in recent history, behind only Ross and Rachel from Friends. Entertainment Weekly has also ranked them number one in their list of greatest TV couples. E!Online has included them in their ranking of 50 greatest romances in television history while US Weekly, MTV and TV Guide has also included them in their rankings of best and most beloved TV couples ever.

Jim and Pam's devotion to each other as well as their friendship which gradually blossomed into a committed and loving relationship has hooked The Office fans since the beginning. Amidst the craziness, high jinks and the absurdity of characters on The Office, Jim and Pam's romance provided a more grounded and emotional reprieve as they are considered the heart of the entire show.

Fans were overjoyed when Pam had finally broken up with Roy but were enraged when Jim got into a relationship with Karen Filipelli in season three. Their relationship was extremely disliked for the sole reason that Karen was not Pam. However, when Jim and Pam finally got together at the end of season 3 and began dating in season 4, it was considered one of the happiest and most earned moments in The Office history.

In season nine, when Jim and Pam were undergoing marriage troubles, it once again split the fandom as it had become difficult to watch. Fans were relieved when they finally reconciled and proved that their love for each other was as strong as ever. These issues and how they overcame them has made Jim and Pam one of the most realistic and relatable couples on television.

According to analysis done by The Talk, Jim and Pam's relationship had also redefined the portrayal of office romances in TV and movies which is usually shown to be steamy, forbidden and passionate. Theirs is a romance born out of shy companionship built on a base of friendship and laughter as they had fun together and trusted each other completely. This is what separated them from traditional office romances and what drew a lot of fans to their story.
