While televisions have existed since 1928, regular scheduled broadcasts of television programs did not begin until the late 1940s. So before the 1950s, it was common not to own a television and therefore most people's feelings about it would be fairly neutral. This changed as televisions became cheaper and more people started owning them, meaning that if someone didn't own a television, it was generally because they couldn't afford one. This might lead to someone feeling embarrassment when admitting they don't have a television.&lt;/div&gt;&lt;/td&gt;&lt;td class='diff-marker'&gt;&amp;#160;&lt;/td&gt;&lt;td style=&quot;background-color: #f9f9f9; color: #333333; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #e6e6e6; vertical-align: top; white-space: pre-wrap;&quot;&gt;&lt;div&gt;This comic is [[:Category:Charts|yet another graph]], describing how people who don't own a television feel throughout several time periods.

[[Randall]] suggests &lt;/del&gt;that &lt;del class=&quot;diffchange diffchange-inline&quot;&gt;these &lt;/del&gt;people &lt;del class=&quot;diffchange diffchange-inline&quot;&gt;would feel &lt;/del&gt;smug &lt;del class=&quot;diffchange diffchange-inline&quot;&gt;because they are resisting a popular trend (owning &lt;/del&gt;a &lt;del class=&quot;diffchange diffchange-inline&quot;&gt;television) which the rest &lt;/del&gt;of &lt;del class=&quot;diffchange diffchange-inline&quot;&gt;the public take part in&lt;/del&gt;. The &lt;del class=&quot;diffchange diffchange-inline&quot;&gt;graph tails downwards at the end, suggesting &lt;/del&gt;that &lt;del class=&quot;diffchange diffchange-inline&quot;&gt;Randall believes that people are becoming less smug. This could be because of &lt;/del&gt;the &lt;del class=&quot;diffchange diffchange-inline&quot;&gt;abundance of video content and other forms of entertainment on the internet and mobile devices. So, according &lt;/del&gt;to &lt;del class=&quot;diffchange diffchange-inline&quot;&gt;Randall, people are returning to not owning &lt;/del&gt;a television &lt;del class=&quot;diffchange diffchange-inline&quot;&gt;simply &lt;/del&gt;because &lt;del class=&quot;diffchange diffchange-inline&quot;&gt;it's not necessary and these people therefore feel neutral towards their lack of a television&lt;/del&gt;.&lt;/div&gt;&lt;/td&gt;&lt;td class='diff-marker'&gt;+&lt;/td&gt;&lt;td style=&quot;color:black; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;&quot;&gt;&lt;div&gt;Gradually&lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;, this attitude began to change. The graph puts the low point of embarrassment some time around the late 1960's or early 1970's. At this point&lt;/ins&gt;, television ownership &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;was becoming common enough that the medium was increasingly seen as primarily consisting of low-brow entertainment, with little to recommend it (FCC chair Newton N. Minow famously described television content as &amp;quot;a vast wasteland&amp;quot;). At the same time, televisions became increasingly inexpensive, &lt;/ins&gt;until &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;they were considered a standard feature in &lt;/ins&gt;nearly every household&lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;.&amp;#160; As a result&lt;/ins&gt;, not &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;owning a television increasingly became seen as a deliberate &lt;/ins&gt;choice rather than &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;evidence of &lt;/ins&gt;poverty. &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt; Sometime &lt;/ins&gt;around &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;1980&lt;/ins&gt;, &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;Randall sees perception shifting to where choosing &lt;/ins&gt;to &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;avoid television is seen as &lt;/ins&gt;a &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;decision &lt;/ins&gt;that people &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;are &lt;/ins&gt;smug &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;about, rather than &lt;/ins&gt;a &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;source &lt;/ins&gt;of &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;embarrassment&lt;/ins&gt;. The &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;implication became &lt;/ins&gt;that the &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;only reason not &lt;/ins&gt;to &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;own &lt;/ins&gt;a television &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;is &lt;/ins&gt;because &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;you have better things to do than watch TV&lt;/ins&gt;. &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt; &lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;

However in recent times television has become imbued with new technologies such as Internet access (known as smart TVs) &lt;/del&gt;and &lt;del class=&quot;diffchange diffchange-inline&quot;&gt;thus owning a television is seen as trendy again&lt;/del&gt;, &lt;del class=&quot;diffchange diffchange-inline&quot;&gt;thus the level of smugness drops.&lt;/del&gt;&lt;/div&gt;&lt;/td&gt;&lt;td class='diff-marker'&gt;+&lt;/td&gt;&lt;td style=&quot;color:black; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;&quot;&gt;&lt;div&gt;&lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;This &lt;/ins&gt;point of view is seen as &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;peaking around 2000&lt;/ins&gt;, and &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;then declining&lt;/ins&gt;, to &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;where people nowadays are more likely to &lt;/ins&gt;be &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;smug about lack &lt;/ins&gt;of &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;TV ownership than embarrassed&lt;/ins&gt;, &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;but less so than in &lt;/ins&gt;the &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;past&lt;/ins&gt;. &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;There are a &lt;/ins&gt;number of &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;possible reasons for this&lt;/ins&gt;, &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;but &lt;/ins&gt;the &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;biggest is probably &lt;/ins&gt;the &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;rise &lt;/ins&gt;of &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;multiple devices and streaming services&lt;/ins&gt;, &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;meaning &lt;/ins&gt;that &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;shows and movies can be consumed on &lt;/ins&gt;on &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;tablets&lt;/ins&gt;, &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;phones&lt;/ins&gt;, &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;and computers&lt;/ins&gt;, &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;making televisions less ubiquitous&lt;/ins&gt;. &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;Not owning a television no longer indicates that you don't consume &lt;/ins&gt;shows and &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;films&lt;/ins&gt;, &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;but simply that you consume them in different ways&lt;/ins&gt;. &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;As a result&lt;/ins&gt;, the &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;trend &lt;/ins&gt;is &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;back toward neutrality: whether you own &lt;/ins&gt;a television &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;or &lt;/ins&gt;not &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;just isn't much of &lt;/ins&gt;a &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;statement anymore&lt;/ins&gt;. &amp;#160;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;

In the 1950s and 1960s&lt;/del&gt;, &lt;del class=&quot;diffchange diffchange-inline&quot;&gt;television was a major source of news and information. Those without televisions might feel that they were missing out of &lt;/del&gt;the &lt;del class=&quot;diffchange diffchange-inline&quot;&gt;important stories of the day&lt;/del&gt;. &lt;del class=&quot;diffchange diffchange-inline&quot;&gt;Also, the limited &lt;/del&gt;number of &lt;del class=&quot;diffchange diffchange-inline&quot;&gt;stations and lack of recording devices meant that discussions of the previous night's television programming was far more inclusive&lt;/del&gt;, &lt;del class=&quot;diffchange diffchange-inline&quot;&gt;with more people watching &lt;/del&gt;the &lt;del class=&quot;diffchange diffchange-inline&quot;&gt;same programs at &lt;/del&gt;the &lt;del class=&quot;diffchange diffchange-inline&quot;&gt;same time. Until the advent &lt;/del&gt;of &lt;del class=&quot;diffchange diffchange-inline&quot;&gt;PVRs&lt;/del&gt;, &lt;del class=&quot;diffchange diffchange-inline&quot;&gt;the prior night's television programming was a popular &amp;quot;water cooler&amp;quot; topic (i.e. something discussed socially at the office the next day). This means &lt;/del&gt;that &lt;del class=&quot;diffchange diffchange-inline&quot;&gt;that those who had missed out &lt;/del&gt;on &lt;del class=&quot;diffchange diffchange-inline&quot;&gt;those programs might feel socially &amp;quot;out of the loop&amp;quot;.&lt;/del&gt;&lt;/div&gt;&lt;/td&gt;&lt;td colspan=&quot;2&quot;&gt;&amp;#160;&lt;/td&gt;&lt;/tr&gt;

So&lt;/del&gt;, &lt;del class=&quot;diffchange diffchange-inline&quot;&gt;someone might feel more smug for not watching so-called &amp;quot;mindless television&amp;quot;&lt;/del&gt;. &lt;del class=&quot;diffchange diffchange-inline&quot;&gt;Similarly&lt;/del&gt;, &lt;del class=&quot;diffchange diffchange-inline&quot;&gt;as television viewership increased from the 1950s through &lt;/del&gt;the &lt;del class=&quot;diffchange diffchange-inline&quot;&gt;2000s, it &lt;/del&gt;is &lt;del class=&quot;diffchange diffchange-inline&quot;&gt;possible that other activities such as reading has decreased; especially given that the younger generation today don't remember &lt;/del&gt;a &lt;del class=&quot;diffchange diffchange-inline&quot;&gt;time without &lt;/del&gt;television&lt;del class=&quot;diffchange diffchange-inline&quot;&gt;.

Specifically, as the rate at which people adopt TV ownership accelerates (positive second derivative of TV ownership rate with respect to time), people who don't own one feel embarrassed (negative smugness); and as the market is saturated and the rate at which people adopt TV ownership slows down (negative second derivative of TV ownership rate with respect to time), people who don't own one feel smug (positive smugness).
