To demonstrate how marketers have adapted to media innovations through the last century and created measurements for them, IfbyPhone created the following infographic about the evolution of the "growth hacker" from the 1920s to today.

"Growth-hacking refers to the use of marketing strategies backed by data to generate growth," says Irv Shapiro of IfbyPhone.

One example of growth-hacking shown in the infographic comes from the 1920s and 1930s. As radio emerged and grew in popularity so did paid radio ads. The first paid ad went on air in August 1922, and Arthur Nielsen, an American market analyst, developed the Nielsen Radio Ratings to analyze the radio market and radio programming.

Among other highlights...

The first TV ad runs in 1941 for $9, and the Nielsen Radio Ratings system is adapted to measure TV audiences with viewer diaries and set meters.

The World Wide Web launches in the 1990s, and impressions and click-through measurements are born shortly after. The first Web ad appears in 1994.
